You own the order of your tour. Photos sit in the order you add them, and you drag any card to move it. Nothing reshuffles your sequence behind your back.
Avenue 510 does read each photo to recognize the room, and you will see a scene label on the card. That label is used for one thing: picking a fitting camera movement for that shot. It never changes the order.
For a listing that reads well, lead with your strongest exterior, run the key interior spaces through the middle, and close on a shot worth lingering on. See choosing the best photos for more on selection.
