There could be others, but the only references to exit codes that I am aware of
are in 'perldoc perlrun' and 'perldoc -f die'.
As far as I can see, the only exit code that perl itself assigns is when
compilation fails, or it detects a run time error, and the only one I recall
seeing is 255. Other exit codes are as a result of calls to die or exit by the
script (including any modules used), including the implied exit(0) when it
falls off the end.

It might be worth looking for alternate method of achieving your desired
result, which isn't entirely clear.
