Auction House does not sort

I have tried sorting the AH by all of the possible options (Item, Bid, Buyout, Time Left) in ascending and descending order and it does not sort any of the auctions.

I don't know if this has been addressed yet or not, or that it is just a feature that is not currently implemented into the current beta patch, but I was just browsing the AH trying to find an item to buy at the lowest price and I noticed I couldn't sort it.
