You are using the version of sort that comes with textutils-2.0
or newer and have reported a problem whereby it is sorting in
some non-ASCII order.
That is due not to a bug in sort, but to the fact that you have
set environment variables that direct sort to use improper locale-
specific tables (you probably have LC_ALL set to en_US).
You should set LC_ALL to POSIX
# If you use bash or some other Bourne-based shell,
export LC_ALL=POSIX
# If you use a C-shell,
setenv LC_ALL POSIX
and then sort will work the way you expect.
