IMDB lists all awards of movies. Here is a list of them:

EMM could fetch that list, let us whitelist the awards we want (nominated and winner maybe too) and transform these into movie tags.

In addition it is probably not a bad idea to transform the name of the awards like:

original: Best Achievement in Music Written for Motion Pictures

custom:

Oscars - Best Music
