I just tried it using this:
and used the different "Sort by" drop down and they all worked for me. Watch the results carefully they do change and may take a second or so to load the selection. Note that the browser page will not refresh as the results are dynamically displayed as you select the different selections.
Let me know if it still doesn't work for you.
I did a search for printer reviews. A list was presented sequenced by relevance (I think it was alphabetically). Attempts to present the results in a different sequence (editor rating, low price) failed - the sequence remained by relevance. This limits the usefulness of CNET printer reviews for my researching what printer to buy.
