Ok, I've deciphered what the initial part of the script does, and I've added some stuff to it which I will post separately once I understand this last bit of the script. I just need some help with the last bit before I try and put everything I've learned together. I've put some comments in the code below about bits I'm confused about. This is the last bit of the script which does the match. 
 @titlewords = @new;  #switch the @new array back to the name @titlewo
+rds now that the exceptions are in place

 my $desired = 5;      # Desired matching number of words

 my $matched = 0;       # Why is this set to 0? How does it change dur
+ing the comparison

 foreach my $csv2 (keys %csv2hash) {

    my $count = 0;    #Again why is this set to 0 at this point? I can
+ see that it's used later and compared to $desired, but how does it i
+ncrease in size past 0 during the operation?

    my $value = $csv2hash{$csv2};  # How does this represent the value
+? There doesn't seem to be any code which counts the words here?

    foreach my $word (@titlewords) {

            my @matches   = ( $value=~/\b$word\b/ig );

            my $numIncsv2 = scalar(@matches);

            @matches      = ( $title=~/\b$word\b/ig );

            my $numIncsv1 = scalar(@matches);

            ++$count if $value =~ /\b$word\b/i;

            if ($count >= $desired || ($numIncsv1 >= $desired && $numI
+ncsv2 >= $desired)) {
                $count = $desired+1;

                last;

            }

    }

    if ($count >= $desired) {

      print "$csv2\n";

      ++$matched;

    }

  }
print "$_\n\n" if $matched;
}                                                                     
+                                           close CSV1;
