You need to understand what this code does: 

#!/usr/local/bin/perl -T
use warnings;
use strict;
use Scalar::Util qw( tainted );

print "ARGV: " . ( tainted( @ARGV ) + 0 ) . "\n";
print "ARGV[0]: " . ( tainted( $ARGV[0] ) + 0 ) . "\n" if defined $ARG
+V[0];

When run as ./program foo you get this: 
ARGV: 0
ARGV[0]: 1

Taintedness is a property of a scalar. An array is not tainted, but the scalar elements of it are. You need to untaint the elements of your arrays that are being passed as arguments.
