Yeah.  sre.DIGITS up until the 2.0beta didn't contain 7.  Took me a long
time to track that one down  :)  I sent in a patch which has been applied
to the newer distributions.

If you don't want to upgrade, just fix DIGITS in sre_parse.py.

P.S.
  Looks like you are doing Prosite searches of protein sequences.  You
might want to look into biopython.org which includes, among other things,
a Prosite to (s)re converter.
