Are they sure that the parking brake handle was in the "set" position. Knowing the Airbus, the handle isn't probably directly connected to anything. It probably signals a computer to set the brakes. What if the computer was broken or the switch in the handle was bad? The FDR probably doesn't record the actual position of the brake handle. Just trying to give the benefit of the doubt to the crew.
By the way, when I was at Skywest, there were stories of crews landing with the parking brake set. In most of these cases it was crews transferring hydraulic fluid from one system to the other inflight by cycling the parking brake. After they were done transferring, they left the brake set and it was downhill from there!

I was also surprised that you could set the brake while in flight and the brakes would actually set.
On the wheels page you have an indication that the brakes are released and the anti-skid is armed after you put the gear down. Helps to take a peek at that when it pops up to see you actually have the auto-brakes set and the anti-skid is armed. Not sure what the indication would be there if the brakes are set.....I'm assuming the bars would be amber showing you that either the brakes are set or the anti-skid is not armed. I guess Airbus needs an ECAM warning if the brakes are set in-flight and the gear is down.

All this talk about the -80 autobrakes. I've never tried it, but can you even arm the autobrakes in TO in the air on the -88? Will you get a yellow disarm light on the panel?
Edit: Just answered my own question. The autobrake system will not arm in TO with the flaps set greater than 26 degrees. Looks like you can't land with the autobrakes in TO on the -88 unless there's something wrong with the system.
