Detailed Transaction Fee Data

[Melbustus]

I'm looking for a resource to better understand how transaction fees are influencing the probability of being included in the next, n+1, n+2...etc block.

Something that spits out a sorted list of transaction fees for a given block would be great. Anything like that exist? If not, it'd obviously be easy enough to write against blockchain.info's API or similar; just don't want to re-invent the wheel.
