I have a bunch of curves that go different directions. However some of the points are out of order. Is there a way to fix the point sort procedurally?

If your screenshot represents a single curve try Sort SOP/By Vertex Order
Which will order points the same way as vertices within the prim

If the screenshot is 3 curves then what sort of order do you imagine?

Yeah I tried point sorting by vertex order and it works for some curves and not for others for whatever reason. Doesn't work for this particular one in the screen shot. If I were to sort by the X direction obviously that would work but wouldn't for curves that go many other different directions.

From left to right in this case for this curve I want 0,1,2,3 and or 3,2,1,0 to be the point order.

You might have to use a polypath to combine all the primitives together into a single curve primitive before the vertex sorting.
