Command-based scoring: cylinder surface flux

I would like to use command-based scoring to obtain the flow passing through a
cylindrical mesh.
In the geant4 source code (version 10.07) I found the required command
(/score/quantity/cylinderSurfaceFlux). However, it was commented out.
I removed the “//” in,
G4ScoreQuantityMessenger.hh and and reinstalled
Geant. Now I can use the scorer. However, the output does not contain any
values, while /score/quantity/flatSurfaceFlux used with a box mesh contains

Is this a known problem and the reason why cylinderSurfaceFlux was commented
out? Is there an other option to get the surface flux on a cylindrical mesh?

Thanks in advance!
