I want to sort strings assuming the 'dictionary' order of the chars is

It appears linux sort also has the problem (LC_ALL is blank).
Any ideas? I want to avoid a brute force char by char sort if
possible.

Please provide an *example* of your data, what it would look like if
sorted "properly", and what it actually looks like after being sorted.

unsorted:
22
2-2
2-3
23
21

linux sort produces:
21
22
2-2
23
2-3

desired sort:
2-2
2-3
21
22
23
(in ASCII order: hyphen (ascii 45) then 0-9 (ascii 48-57) then A-Z
(ascii 65-90))

TIA
