No, that file didn't exist.  In fact, the only part of that script that
was actually recovered was the source code mentioned (which while
generic, was formatted identically so I assumed that was the source of
the code).  The tripwire database being compromised is not a possibility
as it resides in an external database heavily seperated from the machine
in question.
