Score upset the creators (11)
I believe the answer is:
orchestrate
'score' is the definition.
(I know that orchestrate is a more specific form of the action score)
'upset the creators' is the wordplay.
'upset' indicates anagramming the letters.
'the'+'creators'='thecreators'
'thecreators' is an anagram of 'ORCHESTRATE'.
(Other definitions for orchestrate that I've seen before include "Arrange scores" , "Arrange (for maximum effect)" , "Organise (a complex enterprise)" , "Arrange for a full band" , "Organise (music)" .)
