Music for film perhaps that shows number of points? (5)
I believe the answer is:
score
This clue is a double definition.
'music for film perhaps' is the first definition.
(film score)
'that shows number of points?' is the second definition.
(as in the score in a game)
(Other definitions for score that I've seen before include "Result" , "Number of goals/points" , "Tally in a game" , "Number of runs" , "Tally; group of twenty" .)
