Most likely, your problem is not a bug in sort, but a difference in
locales.  A common scenario is that people are surprised to learn that
the en_US.UTF-8 locale sorts case-insensitively while ignoring
punctuation, rather than in ASCII order.

Run 'find . | sort --debug' for more information, as well as 'find . |
LC_ALL=C sort --debug' to see the difference the locale makes.

Assuming that you are repeating the same non-bug of locale differences
as has been frequently reported by others, I'm marking this as not a
bug.  But we can reopen it if your further investigations find something
other than your locale affecting things.

It may also be that busybox sort does not properly honor locale
variables as required by POSIX, but that would be a problem in busybox,
and not something we can fix here.
