Thanks, I suspected that an advanced query might be needed. Since posting this question, I realized that I probably didn’t want to sort the list of tagged pages. Instead, I want to sort them based on when they were last accessed or modified. I did some searching and found a ready-made query which sorts the results based on when a page was last edited, for the code, click here. The page you posted looked promising, but I don’t know the first thing about writing advanced queries.
I think that query I found comes close enough to what I want to achieve. Help is still much appreciated, if someone feels like contributing.
