Music for a movie — something to settle? (5)

I believe the answer is:

score

I believe this clue is a double definition.

'music for a movie' is the first definition.
(I've seen this in another clue)

'something to settle?' is the second definition.
(I've seen this in another clue)

(Other definitions for score that I've seen before include "marks" , "Musical composition in written form" , "Nick; twenty" , "Number of goals/points" , "Mark; twenty" .)

I've seen this clue in The Guardian.
