Mark for each to beat it (7)

I believe the answer is:

scarper

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

'beat it' is the definition.
I can't tell whether this definition defines the answer.

'mark for each' is the wordplay.
'mark' becomes 'scar' (mark left by an injury).
'for each' becomes 'per' (per person).
'scar'+'per'='SCARPER'

'to' is the link.

Can you help me to learn more?

(Other definitions for scarper that I've seen before include "Damage" , "Escape" , "Clear off!" , "Run away (colloq.)" , "bolt" .)

I've seen this clue in the Sydney Morning Herald.
