Strange, this list:

s, S, s, a, B

in Excel, Numbers, and in Araelium Edit comes out as this when sorted

a, B, s, S, s

TextWrangler puts them as

a, B, s, s, S

Ruby sorts  ['s','S','s','a','B'].sort as

["B", "S", "a", "s", "s"]

MySQL (as I have it set up) sorts like the OS X apps.

Trying to do a binary search with a ruby array based on text sorted by 
something else is getting hosed.

Oh... duh, have Ruby sort it :-P

Could get very expensive, but I guess I'll have to do it.
