Question GPWS, Windshear, TCAS

All three occur at the same time, which one do you give priority to? Hypothetical I know and correct answer it seems is W/S, GPWS and then TCAS.
Understand the TCAS having last priority as the other aeroplane would also be given a TCAS warning.
The other two.......I was thinking GPWS first because in the Airbus it is full back stick and TOGA with Alpha Floor protection in normal law. Also W/S recovery procedure is to follow SRS and in some cases that can demand a pitch down ie into the terrain in this case.
Can anyone shed some light on why W/S first rather than GPWS and if the Airbus design would predicate a different response.

Thx
