There is currently no built-in mechanism to manage points. We've seen some people put point values in the task text. In this version, we're trying to keep things really simple.
After having a play I think the idea of placing points in the task text works well. I can also tally up all the points and place them in the sprint name, which can then also be renamed at the end of a sprint to show how many points were estimated against how many were actually completed.
