Settle musical scores? (7)

I believe the answer is:

arrange

I'm a little stuck... Click here to teach me more about this clue!

'settle' is the definition.
(I know that settle is a more specific form of arrange)

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for arrange that I've seen before include "Marshal" , "Organise, plan" , "Place in order" , "Rare nag (anag.)" , "Set in order" .)

I've seen this clue in The Times and The Sun.
