Thank you for your report.  However this matches a very common
signature that is not a bug in sort but a problem with your locale
setting that instructs sort to fold case and ignore punctuation.

What is your locale setting?

  locale

Try setting your local to C (aka POSIX) and try again?

  LC_ALL=C sort SOMEFILE

Personally I use the following settings.

  export LANG=en_US.UTF-8
  export LC_COLLATE=C

This is a frequently given answer.  More information may be found in
the FAQ at this URL.  Look for "Sort does not sort in normal order!".
