Good score, for a predator (5)
I believe the answer is:
eagle
I believe this clue is a double definition.
'good score' is the first definition.
(I've seen this before)
'predator' is the second definition.
(eagle is a kind of predator)
'for a' acts as a link.
(Other definitions for eagle that I've seen before include "Erne, perhaps" , "Hook-billed bird of prey -- old US $10 coin" , "Fine achievement on course" , "Bird with hooked bill and long broad wings" , "drugs with silver left inside" .)
