Go to Orton's office and get into a dialog with Zeke and Koslov. This will initiate a brawl, either pin or KO both opponents to end the cutscene. Weapons are especially handy in this mode.
Talk to Orton after defeating his henchmen, and he will refuse to put you in the title match. This puts you in another brawl during which you have to make Randy say "I Quit" after putting him in the STF. You need to weaken him enough to make him succumb. Hit your standing finisher, the Attitude Adjustment, on Orton at least three times.
Attack Orton's knees with ground attacks, knee breakers and low attacks. Turn Orton over until he's facing down to use the STF, and press "Y" to perform your ground finisher when the finisher bar is flashing.
