You're right.

Although the BVH specifies the rotations in the order Z X Y, they need to be
actioned in the reverse order Y X Z.

I'm currently working on a Perl script that will read a BVH file and
automatically create files equivalent to these inc and dat files. Watch out
for it on binaries.utilities.
