Score hits (3,3,6)

'hits' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'score' is the wordplay.
I cannot really understand how this works, but
'score' could be 'twenty' (synonyms) and 'twenty' is present in the answer.
The remaining letters 'thetop' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
