Team needed to score 147? (3,6)

I believe the answer is:

all blacks

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

'team' is the definition.
(I've seen this before)

I don't understand the remainder of the clue.

(Other definitions for all blacks that I've seen before include "side" , "The New Zealand national rugby team" , "Colourless New Zealand rugby team?" , "New Zealand international rugby team (3,6)" , "High-scoring fifteen" .)

I've seen this clue in The Irish Times.
