Their planes were ordered with the CF6-80E1A3, all of them, if I'm not mistaken. The 333s are the HGW variant, although it is possible to engine it with 68,000 lbt engines I don't know why you would if the better thrust was available.
If this is a new engine type, it deviates from the original order as well.
GE's website has no information on an E1A4B, only the A4.
edit: I see what you're talking about on their website. It clearly says the 333s have A4Bs, and the 332s are mixed A3s and A4Bs.
I guess they decided they could run their 333 mission profile with only 68,000 lbt engines.
