The ListPages module should provide an option to sort pages based on their Wilson score confidence interval in order to provide a more natural way to rank pages.

The current page ordering option order="rating desc" provides only sorting by the difference between the number of upvotes and downvotes on each page, but that ordering can be misleading when there is a large difference between total number of votes on different articles.

As an example: if page A has 5500 upvotes and 4500 downvotes (total score of 1000, but only 55% positive), and page B has 900 upvotes and no downvotes (total score 900, but 100% positive), then this ordering would put page A before page B, even though B is better than A. This is discussed in detail in this article: http://www.evanmiller.org/how-not-to-sort-by-average-rating.htm along with information on how exactly to implement this type of ranking.
