No, I don't know much about scorers - but thank you - we'll investigate.

Please, see the example examples/extended/optical/wls
The simplest way is for you to define two volumes that are smack at the end of your fiber (with the same material as would otherwise be there) and count the optical photons that enter those volumes (and then kill them). You do that in SteppingAction. The safest way is to ask for a PreStepPoint in one of the volumes and the step-length to be > kCarTolerance.
Since G4 10.0 you can also define a dielectric_metal surface with 100% detection efficiency between the fiber and those volumes and define those volumes as SD.
