I did test it (see code below). It seemed to work for me but I see from some of the comments that it can be used in a much better way.

#!/usr/bin/perl -w

use strict;

my @ServicesOnMachine = qw(NetworkManager acpid anacron atd auditd aut

my @ServiceCheckList = ("spray", "echo", "daytime", "discard", "charge

foreach my $service (@ServiceCheckList) {
  if (grep($service, @ServicesOnMachine)) {
    print "$service matches\n";
  }
}

Correction

foreach my $service (@ServiceCheckList) {
  if (grep(/^$service$/, @ServicesOnMachine)) {
    print "$service matches\n";
  }
}

Thanks!
