Mac OS sorts file names in a "natural" way since a very long time 
(since Mac OS 8 I believe). By natural, I mean that numbers inside the 
file name are sorted in numeric order while the rest is sorted 
character by character. For instance "My File 2" will go before "My 
File 10" in file listings because "2" is less than "10".

There's an option in NSString comparison methods to use this ordering, 
but it's not the default.
