Along with perhaps one of the most beautiful score in movie history to accompany, High Road to China is a wonderful and timeless movie.

Should it be scores or score? If you substitute with soundtrack should it be soundtracks or soundtrack?

Thanks Fulvio Emotion: smile
It should be scores. A movie score is the music played to accompany the film.

Scores. It doesn't matter what you substitute. It will have to be plural.

It makes no sense to say one of one thing. If you say "one of X", you mean one out of the group of all X's. You don't, for example, choose one cake out of a 'group' of one cake, nor choose one person out of a 'group' of one person.
