Evaluate the tangent vector of each curve, and then take the dot product of that vector and the x vector. If the dot product is 1 or -1, the lines are parallel to x; if the dot product is 0, the lines are perpendicular. That should be easy enough to test, allowing you to to produce a boolean you can use to dispatch the curves.
