If you simply need to invoke a script every once in a while (say, 1 hour), you can pretty much get by without the aid of special modules. Simply, have a main loop in your script, inside of which you'll spawn off a process and sleep for 1 hour and then repeat this cycle all over again. 
my $script = 'foobar.pl';
my $sleep_time = 60*60; # sleep for 1 hour.
while (1) {
  system("foobar.pl");
  sleep($sleep_time);
}

UPDATE: However, for complex scheduling, I suggest you take a look at the Schedule-Cron module. So, your script might look as following: 
 use Schedule::Cron;

 sub run_scripts {
    system("foobar.pl");
 }
 
 # Create new object with default dispatcher
 my $cron = new Schedule::Cron();

 # Add dynamically  crontab entry
 # invoke run_scripts() every 0 minute past
 # each hour.
 $cron->add_entry("0 * * * Mon-Fri", \&run_scripts);

 # Run scheduler 
 $cron->run(detach=>1);
