I tried Apache for Windows and active perl and is OK.
I think that in a general context; if you don't neeed PerlScript but only Perl, Apache server may be the solution.
It would be a good idea to use a perlwrapper for CGIs in Windows.
This perlwrapper takes care of the url which the server is asked for, and then execute the perl code.
It catch the result of the execution and then send it to the browser.
It can be a little slower, but is much more safe, cause is more difficult to attack the IIS
