I can assure you that PT is exporting BWAVs in SMPTE order. They show up in Soundminer, every DCP creation software I've dealt with as SMPTE. Even QT X shows it as SMPTE and Reaper as well.

Yup,
It's because Pro Tools buses internally to the QuickTime engine that does the actual rendering of the file in this case. And because Pro Tools internal bussing is in film order it gets rendered as a film order QuickTime. It's neither Pro Tools' fault neither QuickTime's, it's just an annoying compatibility/crossover issue. 5.1 multichannel files created by the Pro Tools file API (recordings/bounces/exports) are in SMPTE order, absolutely definitely, have investigated the actual byte structure of the files themselves several times over the last few years to verify this.
