First of all, you go to Firefox's Tools -> Page Info menu item and click on the "Forms" tab to see what forms are present in the page. In this case it looks like the second form is the login form. It doesn't have a name so you have to identify it by number.

Then use the submit_form example from the WWW::Mechanize documentation (which your first attempt seems to be based on): 

use strict;
use warnings;

use WWW::Mechanize;
my $m = WWW::Mechanize->new( autocheck => 1 );
$m->get("https://www.bittorrent.com/account/signin");

$m->submit_form(
      form_number => 2,
      fields      => {
         username    => 'mungo',
         password    => 'lost-and-alone',
      }
);

print $m->content;

This seems to work as it returns a page with the text: "The username and password you entered does not match a registered user."
