Put more effort into faking the User-Agent, e.g. $ua->agent('Mozilla/5.0 (Windows; U; Windows NT 5.1; cs; rv:1.8.1.15) Gecko/20080623 Firefox/2.0.0.15'); works fine. Authors of the page obviously try to be too clever and decide what version of the page you get according to the user-agent header.

That seems kinda weird, when they only serve a <noscript> which was designed to allow you to present both script-enabled and simple version of the document at once...
