That's an issue with your locale. Probably between your upgrade from
earlier Fedora to F13, your environment was changed to export
LC_ALL=en_US or some such, whereas you were previously used to LC_ALL=C
(or at least LC_COLLATE).

Correct is in the eye of the beholder. This is a frequently reported
non-bug, at least on the upstream bash list.

zsh doesn't follow collation rules when expanding  globs; but bash
does. POSIX says that the expansion of  outside of the C locale is
implementation-defined, so either behavior is right.

Yes, it depends on the locale env vars.
