I've already done something along this lines with my Fractal Tune Smithy
program - it has a drop list of all the scales in the Scala archive,
and you can sort it in various ways.

I'm also interested in adding more sort options.

You can then save the sorted list, and here is the start of one of them:

+1 492.000 cents 625.000 cents African Mboko Mouth Bow (chordophone, single string, plucked)
1 400.00000 cents 2/1 ogr2.scl | Optimal Golomb Ruler of 2 segments, length 3
1 3/1 4/1 gradus3.scl | Intervals > 1 with Gradus = 3
1 99/70 2/1 fj-2tet.scl | Franck Jedrzejewski continued fractions approx. of 2-tet
1 32/29 1/2 16/29 chimes.scl | Heavenly Chimes
1 166.01500 cents 332.03000 cents 4/3 cet166.scl | 3rd root of 4/3
1 200.00000 cents 800.00000 cents 2/1 ogr3.scl | Optimal Golomb Ruler of 3 segments, length 6
1 5/4 3/2 7/4 harm3.scl | Third octave of the harmonic overtone series
1 77/61 97/61 2/1 temp3ebt.scl | Cycle of 3 equal beating thirds
1 63/50 27/17 2/1 fj-3tet.scl | Franck Jedrzejewski continued fractions approx. of 3-tet
1 3/2 6/1 8/1 gradus4.scl | Intervals > 1 with Gradus = 4
1 91/90 35/33 219/160 16/3 iter31.scl | Iterated Kidjel Ratio Scale, IE=16/3, PD=3, SD=0
1 5/4 25/16 125/64 2/1 efg555.scl | Genus quartum [555]

That one was sorted by number of notes, so shows the 2 note scales, then 3 notes, then so on,
and within each one, sorts with the one with the smallest step size first, then
for those with same smallest step size, ones with most of the smallest steps first.

Other options are to sort by number of superparticular intervals,
largest superparticular interval, alphabetically by title,
and various other ways

I also did a list sorted by the n-valence, where 2-valent = myhills
property, which you can find in the files area of the TL.

So, mayabe is relevant to your project, and could save some duplicated work, or maybe
we could share ideas.
