While waiting for Ed, you may try Khottabun font for Lao/Esaan Tham script,
another Tai Tham variation used in Lao and northeastern Thailand:

 http://linux.thai.net/~thep/esaan-scripts/fonts/Khottabun.ttf

The font, however, has provided all the reordering rules in GSUB, so that it
can still display on absence of rendering engine preprocessing. It may not be
good for your testing, but you can get some idea of the requirements from it.

A test page, with web font embeded:

  http://linux.thai.net/~thep/esaan-scripts/tham-test-woff.html

It reportedly renders properly on Firefox and IE9, but not on Chrome.
