You do have a syntactical error in the script. One of the lines should read as follows:

eval { kill 0 * $_[0] };

Note the use of square brackets instead of parenthesis.

Also, you asked about why only $_[0] is evaluated. The sub tainted() is apparently intended to take a single scalar as its argument. That scalar is held (loosely speaking) as the first element of the special variable @_. You can read up on that in perlvar and perlsub.
