Make a scratch number of points (5)
I believe the answer is:
score
I believe this clue is a quadruple definition!!
'make' is the first definition.
(I know that make is a more specific form of the action score)
'a scratch' is the second definition.
(score is a kind of scratch)
'number' is the third definition.
(score is a kind of number)
'of' is a link.
'points' is the fourth definition.
(I've seen this before)
(Other definitions for score that I've seen before include "Notch; twenty" , "Cut - and run!" , "Hit - music" , "purchase of illegal drugs" , "marks" .)
