The case-sensitivity looks buggy in sort. Have a look at these examples:
Thanks for the report. However, this is most likely due to your choice
of locale, and not a bug in sort; this is a FAQ:

Using 'sort --debug' will help expose the issue.
$ sort -k1,2 bbb
a B b 0
A b b 1
A B b 0
$ sort --debug bbb -k1,2
sort: using `en_US.UTF-8' sorting rules
sort: leading blanks are significant in key 1; consider also specifying `b'

See the difference? In the C locale, you get ascii sorting (A comes
before B comes before a comes before b), in the en_US.UTF-8 locale, you
get dictionary collation sorting (a comes before A comes before b comes
before B).
