At BA it's 4, 1, 2, 3. Engine 4 powers the primary braking source, that's why it's started first. Engine 1 powers the secondary braking source and engine 2 powers the reserve braking source. Engine 3 doesn't power a braking souce, that's why it's ofter shutdown after landing.

I've read in a 747-200 manual, the best sequence is 3-4-2-1... Not sure about that...
