Thanks for reporting it.  The 'b_zip' is correct in the AuthorizeNet.pm
module but incorrect in the globalsub.  It probably hadn't been noticed
because people are expected to use the payment modules rather than the
globalsubs.

I think the globalsubs are unsupported anyway.  In any case, it's fixed
in CVS now.
