Now that I have that under control, how do I print the output of the script to a file? I cannot figure it out. Thanks in advance and of course here is my coding.

#!/usr/bin/perl -w
foreach $file (@ARGV) {
        open (IN, $file)  or die "Cannot open file '$file' : $!\n";
        while(<>) {
                $line = <IN>;
                @array = split (' ', $line);
                foreach $word (@array){
                        $word =~ s/[^\w\s]//g;
                        $word = lc ($word);
                        $wordcount{$word} += 1;
                        }
                }
        foreach $key (keys %wordcount) {
                print "Word: $key " . ($wordcount{$key}) . "\n";
        }
}
print  ("scriptOutput\n\n");

Now that I have that under control...

If 'that' refers to the lack code tags in your OP, the situation is still out of control. A  <code> tag is closed by a  </code> tag, not by a  </c> tag. Please see Markup in the Monastery. Please check the effects of your changes.

Printing to a file usually involves supplying an output file handle (see open) to the print statement. E.g.:
    my $filename = 'file.name';
    open my $fh_out, '>', $filename or die "opening '$filename': $!";
    my $something_to_output_to_file = your_process();
    print $fh_out "here is something for the file \n";
    print $fh_out $something_to_output_to_file;
    print $fh_out "that's all, folks! \n";
    close $fh_out or die "closing '$filename': $!";
