How can IIS stop it? If your Perl script has the authority to do it; then calling system to use a utility to do will also work unless there is some mysterious mechanism at work.
Beside which, I already told you how to do it. You have to bit-wise OR the new permissions with the existing ones, before (re-)setting them.
