modules permissions after unzipping .par

Hello All,

I have noticed that when I unzip a .par archive the extracted modules do 
not preserve their permissions:

Here is an example:

pp --verbose=9 -o hello.par hello.pl
unzip hello.par

ls -l lib/strict.pm
-rw-rw-rw-    1 salih    other      407 Feb  4 11:29 lib/strict.pm

All the files that was added with addString have very permissive 
permissions.

My question is How can I keep the initial permissions of the modules ?

Thanks in advance,

        -salih
