That's not quite accurate. LANG _can_ affect sort behaviour:

$ printf 'gęś\ngoose\n' | env -i LANG=pl_PL.UTF-8 sort
gęś
goose

$ printf 'gęś\ngoose\n' | env -i sort
goose
gęś


This is what POSIX[0] says about LANG:
>This variable shall determine the locale category for native language, 
>local customs, and coded character set in the absence of the LC_ALL and 
>other LC_* (LC_COLLATE, LC_CTYPE, LC_MESSAGES, LC_MONETARY, LC_NUMERIC, 
>LC_TIME) environment variables.
