Just my two cents here,
for each $word why dont you create a custom regex array instead of just a stopword array? You might like reading this regarding the proper storage of your regexes.
your standard regex could look like something like this: 

#!/usr/bin/perl
my $string = $ARGV[0];
if($string =~ m#(\Aof|of\z)#){
    print "matched out at start or end\n";
}
