Those a player lays down to score (5)

I believe the answer is:
tiles
'those a player lays down' is the definition.
I can't tell whether this defines the answer.
'to score' is the wordplay.
'to' becomes 'til' (I've seen this in another clue).
'score' becomes 'es' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'til'+'es'='TILES'
Can you help me to learn more?
(Other definitions for tiles that I've seen before include "Roofing materials" , "Thin flat slabs, for roofing perhaps" , "Small oblong slabs used in roofing" , "Thin flat slabs of fired clay" , "Glazed rectangles used to cover walls or floors" .)
