What's interesting about "For Your Consideration" versions of film scores, to me anyway, is that they're often different from the commercial release. In the FYC disc passed out for The Social Network, some of the mixes were different, and there was even a track that never made it onto the score that was released on CD, BluRay and vinyl.
For that reason, as well as their scarcity, these FYC discs fetch big bucks on the secondhand market. But we live in an era of streaming now, and so in lieu of mailing a bunch of plastic to people, studios just post FYC versions of scores online for consumption. Yeah, yeah, here's the link to The Killer score as submitted to the folks who are considering who gets nominated for the awards. It's slightly different from the commercial release, as expected. If you're clever, you can inspect the network traffic or the page source code and get links to the MP3s that are being streamed.
You can also just visit this forum and click on the direct links. And if somehow this is your first exposure and you like what you hear - drop $12 on the high fidelity lossless version on Bandcamp.
