Two lists-points and values, finding points/values inside curves and then adding them up in separate groups?

I have a list of points with a separate list of values for the points. Long story short by culling them I produce a grid of curves with quadtree. Now I want to sum all the values inside each curve to use it as vectors for each curve to be extruded. So far I was thinking that I could select the points inside each curve and somehow have a corresponding tree of values that follows it too. From there use the addition in each tree but this is too complicated for my knowledge of grasshopper atm. So I am asking for your help guys.

The aim.
