That wasn't my reading. The OP said the original flight was cancelled and "I was rebooked on the later flight but the ground staff were 50/50 whether that flight would end up being cancelled too". It isn't clear whether the later flight went, but if it did that's what the OP was booked on and should have taken.
I wasn't clear that BA staff at LBA actually organised the taxi, I got the impression the OP decided not to wait and did it on his own volition along with some other passengers, with BA subsequently refunding but again I could be wrong on this point.
The actual section in the t&cs says

14.6. Where a Member is involuntarily re-routed by British Airways onto another carrier, and the original flight on which the Member was booked would have qualified for Avios points, the Member may still claim such Avios points online at Ba.com. British Airways will endeavour to ensure the Member's account is credited with the appropriate Avios points however it may be necessary for details of the Member's itinerary, including the retained segment of the boarding pass and passenger receipts to be sent to the Member's Local Service Centre in order to claim any Avios points credit.
I don't see any re-routing on another carrier, but you may be right and if requested BA could pay. It would almost be useful for the OP to try and report back on the result.
