Nope (I just looked again to be sure
). When I am looking at "Books", "Previews" or "Articles from Pocket" I get the sort options you mentioned. Under "My Collections" I have no options except for the far right where you can add a new collection.
I have even pressed on the grey bar like there was something there, but nothing pops up. And here I thought I was going to miss all the problems people have with Kobo
