Options
The two 31-note scales are musically identical. They just start on different notes.
Same for the two 26-note scales.
You can start the scale on any note, as long as the intervals between notes are preserved.
Although musically identical, they will not play the same music, as the notes are connected to different MIDI numbers.
The 26-note scales are compatible with the John Smith Universal organ.

Options
The given notes are just examples.  You can start the scale on any note, as long as the intervals between notes are preserved.
The registers are all Melody registers (12 notes).  The Bass and Accompaniment play on fixed pipework.
All the Register and Percussion keys are optional.  A basic 25-note organ would contain the 25 notes only.  A 26-note organ might consist of 25 notes plus the Bass Drum, etc. (Although, if you do not intend to add registers and percussion, the scales at the top of the page would be a better option.).
Any combination of Percussion and Register keys can be added, up to the full compliment of 30 keys.  If adding a Side Drum, both sticks must be provided (one on 82 and one on 85).
Registers are operated by a short pulse, and when a register is operated, it will cancel the other 2 registers, unless they are also selected at the same time.  Because of this, any unused register keys must be disconnected entirely, otherwise the selection of an unused register will cancel all the registers!
In my music, the Bourdons and Violins are often selected together, to produce a third extra-loud tone.  If you do not want this, you must provide some circuitry to select the Violins only (rather than the Bourdons only). ie. key 46=Bourdons, key 44=Violins, keys 44+46=Violins.
You could add some variety to the percussion by arranging for the Cymbal to play only when the Violins are selected.

Note that this scale is an extension of the 25-31 key scale above, with identical numbering. So this scale will also play that music.
The given notes are just examples.  You can start the scale on any note, as long as the intervals between notes are preserved.
The registers are all Melody registers (22 notes).  The Bass and Accompaniment play on fixed pipework.
All the Register and Percussion keys are optional.  A basic 42-note organ would contain the 42 notes only.  A 43-note organ might consist of 42 notes plus the Bass Drum, etc.
Any combination of Percussion and Register keys can be added, up to the full compliment of 49 keys.  If adding a Side Drum, both sticks must be provided (one on 82 and one on 85).
Registers are operated by a short pulse, and when a register is operated, it will cancel the other 3 registers, unless they are also selected at the same time.  Because of this, any unused register keys must be disconnected entirely, otherwise the selection of an unused register will cancel all the registers!
In my music, any combination of registers can be selected together (except that the Glockenspiel is never selected on its own).  If you want to prohibit certain register combinations, you must provide some circuitry to achieve this.
The Bourdon Celeste register is often a single rank of pipes tuned Celeste with the Flute register.  If you do it like this, you will need to provide some circuitry to select the Bourdons plus the Flutes whenever the Bourdons are selected. ie. key 49=Flutes on their own, key 46=Bourdons + Flutes.  The Celeste rank must never be allowed to play on its own.
You could add some variety to the percussion by arranging for the Cymbal to play only when the Violins are selected.
