The few I've opened appear to cover a 60-character segment of the ASCII table from 0x20 to 0x5B in row major order with a fixed glyph size indicated in the file name.

There does seem to be consistency in groups with similar names, but e.g. from the first page, two of the same size with different ordering:

Still, it's a good point that there's some ordering. Maybe it's not so bad setting up an index by hand for each group.
