Vertigo has just been released on blu ray. I wonder if it will have an isolated score on the 5.1 mix? Maybe we could get a new version of the OST with all the cues.

The blu-ray doesn't have an isolated score track.

It doesn't have an isolated score track as a special feature, but one track of the 5.1 mix is mostly score with no other sound effects, 99% of the time.
