Agree the score (5)
I believe the answer is:
tally
I believe this is a double definition.
'agree' is the first definition.
(I know that agree can be written as tally)
'the score' is the second definition.
(tally is a kind of score)
(Other definitions for tally that I've seen before include "List" , "Count, add up" , "Count up; match" , "label" , "Reckoning of a debt or of votes" .)
