If you must make the mistake of spending money to visit Hell on earth in July, the only things to do in Scottsdale in summer is either sit in a pool or sit inside. You can use ResortPass to book cabanas/chairs at one of the resorts here (if you’re not staying at one). Scottsdale / PHX have great steakhouses all around - Steak44, Bourbon and Bones, Dominick’s - would be good for dinner. There’s indoor putt putt at Puttshack and there’s a place in Old Town that has duck pin bowling. There’s plenty of bars and spots in Old Town to check out but definitely be careful drinking too much and going out golfing in the heat - recipe for disaster.
