Plain spamassassin script works, spamc/d combination does not. Nope,
this is not necessarily related to any Perl code.
Looking through the full list of upgraded packages, the two SELinux
related ones stick out. In particular, since the client / server
environment is affected, but not the standalone variant of calling the
majority of shared SA Perl code.

Nah. I was talking about the difference in your test (manually starting
spamd) and the environment observed to fail (your dev test rig script).
If you want to debug what might cause spamc/d to fail, you need to
reproduce the environment as close as possible. As is, I cannot even be
sure your manual spamd test and the dev environment do use the same
port, since at least the dev script doesn't sound like root privileges
to me.

Unrelated to the problem at hand, but Fedora 18 and Fedora 20 does not
account for "as near to identical" as reasonably possible.
