"doh!!!"...As usual when I post a question on a Saturday night my brain isn't at 100%......I knew what the problem was when I woke up this morning. Its funny how sleep can clarify things. The problem as I see it, is the precedence of "if" and "or" when using that "trailing if" idiom. So when I added the "or warn", the statement

chmod($dirmode, $_) if (-d $_) or warn $!;

if (-d $_) or warn $!;

would always return true, since warn is always there, and everything, both files and directories were made 0755. My solution is (without Bart's correct fixes about octal() ) : 

#!/usr/bin/perl -w
use strict;
use File::Find;

my $topdir  = shift || '.';
my $filemode = shift || 0644;
my $dirmode  = shift || 0755;

find(\&doit, "$topdir");

sub doit {
 return if $_ eq "." or $_ eq "..";
if(-f $_){chmod($filemode, $_)or warn $!}
if(-d $_){chmod($dirmode, $_) or warn $!}
}
