I proposed an up arrow, a square diamond, and a down arrow, all from the same Unicode set, in a mockup I sent to Lydia. I still think that those are a better idea, and not just because it was my idea.

The problem with arrows is that it might be confused for voting arrows. Another option could be squares of different sizes, but then the smallest one can be hard to click, and the biggest one hard to place.
 
As for sorting statements, for me drag&drop should be the way of doing it. No idea how much would cost to do it...
