I don't think this is a bug, it is documented behavior (p 33 of the manual):

In stock Lua, many things depend on the current locale. In LuaTEX, we 
can't do that, because it makes
documents unportable. While LuaTEX is running if forces the following 
locale settings:
LC_CTYPE=C
LC_COLLATE=C
LC_NUMERIC=C
