Three composers have been ruled out of the running for Best Score by their brethren in the music branch of the Academy. Carter Burwell won't contend at the Oscars for either "True Grit" or "The Kids Are All Right" while Clint Mansell is out of the running for "Black Swan" and Michael Brook was ruled ineligible for "The Fighter."
All four scores were found to rely too heavily on pre-exisitng music. In the case of "Black Swan," the score includes significant samples of Tchaikovsky's "Swan Lake" while "True Grit" makes use of many 19th century hymns. Both scores for "The Fighter" and "The Kids Are All Right" were found to be include too many old songs and not enough new music.
