I took a tube journey to Victoria yesterday, changing to Vic line at

On arriving at Oxford Circus, Vic line was severely delayed due signal

and that tube tickets would be valid on local buses.
How can my ticket be valid on local buses if I'm using PAYG?
Do I just wave my Oyster card at the driver and tell him the tubes are
bunged up?

London Buses have Oyster card readers beside the driver, as well as
near the doors on Bendybuses.

Oyster PAYG single bus fare = £1.20 (cf. cash fare £2)

You're missing the point. I've already paid for my journey by tube. I
should be able to continue my journey by bus for no extra cost.
