Scottish island, for example, backing position (7)
I believe the answer is:
arrange
'position' is the definition.
(arranging is a kind of positioning)
'scottish island for example backing' is the wordplay.
'scottish island' becomes 'arran' (I've seen this before**).
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'backing' is a reversal indicator.
'eg' written backwards gives 'ge'.
'arran'+'ge'='ARRANGE'
(Other definitions for arrange that I've seen before include "Put in order; make plans" , "Set in order" , "Settle, work out" , "Put in neat order" , "Set in place" .)
