I think the confusion is Inkscape is grouping by the tangents and 
POV-Ray by the Bezier spline segments as above.

It should be that each POV-Ray segment has a starting, on curve, tangent 
point and an ending, on curve, tangent point(*) - between which are two 
control points coming from two different Inkscape tangents(**).

(*) - These being <249.99999874, 886.42857827>,  <312.85712126, 
640.71428031> and <109.28570835, 735.00000000>

(**) The pairs being pulled from the six inkscape control points as the 
two between each of 3 pairs of starting and ending on curve points.
