I have geometry from which I need to extract a clean NURBS curve (along some edges)

I can't get a clean result because the points are not ordered in sequence.

Does anybody have a good idea for this?

here is one technique you can use
but you probably need to recreate your edge group according to it
the key is to create ordered point group
look at the file

That's great Thomas. Now I know what the "Create ordered" tickbox is for  

Do you think it would be possible to completely proceduralize the process?

here is the fully procedural method if you have continuous curve without branching as in your case
it's based on neighboring points so it may be better than proximity searching if you have crazy curves

That's excellent. Thanks so much to both of you. I can chew on these files for a while. Great insights.

ant_sort node
to use  it in this case all you need to do is
sort by Y
add the "ant sort" node
then sort by $ANT

make sure the first point (0) is where you want your curve to start,otherwise you will have to shift it and play with it more.
