I'd assume it works on the same algorithm as the home page and normal comment pages. Something of the form: points / (timeSinceEpoch^2) After a certain time the number of points needed to override the denominator is unattainable, no matter how popular the comment was. As a result, the comments on the top of this list should be both popular and recent.
