Huh, what is that?
I've found the description in the grob-interface reference but I don't 
really understand what it does here ...

On first sight it does exactly what I wanted it to do (see first attachment)

The consequence is that the markup doesn't move to avoid collisions (see 
second attachment with lower notes).
If I comment out the cross-staff tweak again the lines move with the 
note heads, but of course the order changes again.

Thank you for these thoughts and inspiration :-) But please don't 
investigate any further, it seems Aaron's suggestion is what I need.
