This is a perl question, not a MacPerl question. The perl newsgroup is a 
better place to ask perl questions. When in doubt use parantheses. I 
don't think this is what you want:
unlink $fullpath if $age > 31 || print "Couldn't unlink $fullpath: $!\n";

I think that is evaluated as:
unlink $fullpath if ($age > 31 || print "Couldn't unlink $fullpath: 
$!\n");

How about this?

#!/usr/bin/perl

die "Usage: newfiles_aging.pl <directory>\n" if !$ARGV[ 0 ];
opendir( DIR, $ARGV[ 0 ] );
@dir = readdir( DIR );
close( DIR );
foreach $file( @dir ){
	$fullpath = "$ARGV[0]/$file";
	$age = (-M $fullpath) || die "Couldn't get age of $fullpath: $!\n";
	if ($age > 31) {
		unlink "$fullpath" || print "Couldn't unlink $fullpath: $!\n";
	}
}
