The score tag isn't returning any value because, on line 782 you have: re = stats.match(/itemprop="ratingValue">([\d.]+?)<\/span>/);
I tried with re = stats.match(/itemprop="ratingValue" class="score-label score-\d">([\d.]+?)<\/span>/); and it's working correctly. They probably changed the html recently.
