Does old-fashioned scribbles (7)
I believe the answer is:
doodles
'scribbles' is the definition.
(I've seen this in another clue)
'does old-fashioned' is the wordplay.
'fashioned' indicates anagramming the letters.
'does'+'old'='doesold'
'doesold' with letters rearranged gives 'DOODLES'.
(Other definitions for doodles that I've seen before include "Aimless drawings" , "Scribbles absent-mindedly" , "rough sketches" , "Makes squiggles on paper" , "makes drawings absentmindedly" .)
