Two unrated books, but one shows up at the bottom, where it should be, and one shows up in the middle, where it definitely shouldn't be:

How would I even notice that book if the filter had happened to include a couple of hundred books, instead of just these few?
The list ought to show rated books in descending order first, and then start over with only community rated books, also in descending order. Same as I convinced you to do with the new tagging dropdown.
