WE have been passed an advance tip on the 1994 New Year Honours list. Last night on ATV, according to our avid TV-watching source, the Post racing writer was giving the benefit of his opinions . . . while under his image appeared the surprising label ''Sir Robin Parke''. We called ''Sir Robin'', who said he was ''rather amazed'', adding: ''Of course I am delighted. It is nice to be suitably rewarded for all the racing tips I have given.'' He said that, on the off-chance that a mistake had been made, the British programme producer might have confused him with Daily Telegraph racing columnist Lord Oaksey, who was here at the same time.
