hmmm ... Lua?

"if both arguments are strings,
then their values are compared according to the current locale"
http://www.lua.org/manual/5.1/manual.html#2.5.2

Plain ASCII sort order by byte value is usually used in the C locale
(but byte values could as well be EBCDIC, so don't count on it).
Depending on your libc, other locales may use proper collations
treating case as a secondary property
(basically kicking in only if values are equal ignoring case).

Try setting LANG, LC_ALL and friends to other locales.
