I playing with Gearman::Client and below are my codes. Basically what I wanted to do is to send a string from the client and have the worker split them and return two strings. 
#!/usr/bin/perl
# worker.pl

use strict;
use Gearman::Worker;

my $worker = Gearman::Worker->new();
$worker->job_servers( '127.0.0.1:4730' );

$worker->register_function( 'split_it',  
  \&my_split_function );
$worker->work() while 1;

sub my_split_function {
    my $string = $_[0]->arg;

    my @new_string = split( ',',  $string );
    return \@new_string;
}

-------

#!/usr/bin/perl
# client.pl

use strict;
use Gearman::Client;

my $client = Gearman::Client->new();
$client->job_servers('127.0.0.1:4730');

my $result = $client->do_task( 'split_it', 'abc,def' );
print "Split: @$result\n";

When I run the client.pl, it will give an error output on the worker.pl something like 
Not a SCALAR reference at
 /usr/local/share/perl/5.8.8/Gearman/Worker.pm line 365.

Does this mean that it is expecting the worker.pl to return a scalar reference? Since I'm trying to return an array reference, then it is failing?
