Sorry for the confusion. I'll give you an example. Here is a listing of a few lines from my map list. Since the macOS Terminal only looks at the first number and doesn't treat numbers as values, 1 will always come before 2 (10 comes before 2).
Rooms - SubMap (8bpc, 10x8) [1,5].bin
Rooms - SubMap (8bpc, 10x8) [1,6].bin
Rooms - SubMap (8bpc, 10x8) [1,7].bin
