Is there a good reason to not keep them in "/etc/mail/spamassassin/"
instead? That would ensure a simple rename can work and be IMO a bit
more in line with what we do else where (like host network changes),
and using "/var/cache" here feels also a bit odd in general, but that
doesn't have to be the deciding factor.

I'm fine with switching to move, but IMO adding a short info for why
not changing the pending changes config file path to the same directory
might be warranted.

is there no error variable?

With rename we could at least do

if (-f $shadow_path) {
    rename($shadow_path, $conf_path) or die "failed to apply custom scores - $!\n";
}

(which would have made exposing that bug much easier in the first place ^^)
