Zoom's deaging maneuver likely won't work, given that he apparently had to come within very close proximity of his opponent(AND [albeit briefly] stay in one place) to preform that trick. Time traveling into Surfer's past also isn't an option, as that equates to a self-BFR and automatic loss, per forum rules.
Zoom's most reliable option here is a good 'ol fashion(and relentless) speedblitz, imo. If a single-panel-long blitz is enough for him to stagger Booster, Supes and Hal, I see absolutely no reason why a more prolonged blitz wouldn't cause damage to the likes of Surfer(FTL blitzes'll do that to even the toughest opposition: see Diana's battle with Zolomon.)
Blitzes aside, Professor Zoom was far, far, FAR faster than either Wally or Barry. Surfer has never fought a being remotely close to Zoom's level of speed-- he isn't touching Zoom unless Zoom wants to be touched, imo. That said, the most likely outcome I see here is a stalemate(sans Surfer's very much out of character 'planetary destruction' card, of course.) /shrug
