I've found that the score applied for Golden torrents is not enough to snatch them reliably. When I set the Prefer Golden setting, I expect it to always choose the Golden release over a Scene release. Here's an excerpt from my log that illustrates this setting failing to grab the Golden release over a Scene release:

02-22 13:56:17 INFO [core.media.movie.searcher] Search for Thor: The Dark World in 720P
02-22 13:56:21 INFO [otato.core.providers.base] Found correct release with weight 1.00, old_score(4581) now scaled to score(4581)

02-22 13:56:24 INFO [tato.core.plugins.release] Snatched "Thor The Dark World (2013) - 720p Blu-ray x264 Scene (720p)": Thor: The Dark World (2013) in 720P

With this modification it will fix this specific example and hopefully all others.
