Film director with a good score when shooting (6)
I believe the answer is:
winner
'film director' is the definition.
(I've seen this before)
'with a good score when shooting' is the wordplay.
'with' becomes 'w' (abbreviation).
'a good score when shooting' becomes 'inner' (type of archery or shooting score).
'w'+'inner'='WINNER'
(Other definitions for winner that I've seen before include "Victor" , "One succeeds" , "film director" , "success" , "Conqueror" .)
