Sort Splitted Surfaces

Good evening everyone.
I have an unknown problem: 

I have split a surface with 6 curves. 2 of them are part of the same branch. I need to flatten the curves before splitting, which somehow takes the order away. 

After been split the surfaces don't have the same order anymore.

What I need:

...in branch (0;0) is the surface between curves 0;0 / 0;0 / 0;1
...in branch (0;1) is the surface between curves 0;1 / 0;2
...in branch (0;2) is the surface between curves 0;2 / 0;3
...in branch (0;3) is the surface between curves 0;3 / 0;4
...in branch (0;4) is the surface between curves 0;4 and outer boundary
...in branch (0;5) all other surfaces

But i can not do it manually with list item because this is just a test, sometimes I have much more curves and the partition before the splitting needs to give the clue, how the surfaces are branched after the splitting.

Does any have an idea how to fix that? I could also be done without splitting, just with the curves, but I don't know how, if everthing needs to stay parametric

Thanks in advance
