Align scales along a loft object

[Fabrice]

Here's an example.
A renderable spline (I also tried with a loft object) a leaves distributed all along.
I'd like the leaves :
- being turned toward the sky
- being aligned to the spline

To be clear, if I create a spline like this one but using tyspline + tymesher it work perfectly, 
I just need to set the rotation node to 'aligne to surface' and specify the same object as the 'orientation object'.
But with a regular renderable spline or a loft object the same parameters wont work.
