I suspect that there's a hidden factor here: the order in which the
'readdir' libc function returns the directory entries.  On GNU/Linux,
the order is arbitrary (AFAIK, it's the order of the entries in the
directory file).  On MS-Windows, the order is alphabetic, so reversing
will produce the reverse alphabetic order.  I don't know what happens
on OS X.
