Yep, I've commented about the lack of "sort by price" before also, they need to add both ascending and descending sort by price. I think I might have put it on the wishlist but not certain.
I definitely would have bought some more games on certain promos if I could have sorted by price. I don't always have the time or inclination to go through an entire list of dozens or hundreds of games to find lowest priced ones though. Perhaps they do this on purpose so the low priced games are a promo worm on the hook so to speak, but while you're searching the haystack to find the needle you spot some other game and go "HOLY SHIT I MUST BUY THIS FOR $20!"
Hard to say, but if I had to hazard a guess I'd say they just haven't thought of it or are too busy working on higher priorities or something. I would literally check a price sort list very frequently to pick up some low hanging fruit, probably games I would never buy otherwise too and end up buying them anyway because they're say... $2 or less and below the "who cares" price.
