I suggest you get zip. This is a program that runs in a shell, and produces the standard format zip-files. Than do something like (I'm not familiar with win32 perl):

system("path\zip","zipfile","filenames_that_youwanna_zip");
[download]

This simply creates the zip archive, free at your convenience.

Hope this helps,
