If hard disk is full, deliver should return EX_TEMPFAIL, not crash.

The error code should be EX_TEMPFAIL = 75, Postfix bounces anything
else.

I'm not too good with Perl, but:

It prints the $? but doesn't forward the exit error code.. Of course, if
only some deliveries fail but others don't, it becomes problematic! I
think in such situation you should return success, and re-send the
failed messages via sendmail.

All of this would be much easier and more robust with v2.0 and LMTP.
