Using ELO would avoid the need to assign explicit points to 1st/2nd/etc. and would likely converge on the "true" ranking more quickly than the current ranking system.

Here's a public domain ranking method that approximates ELO for multiple players:

There's also Microsoft's TrueSkill:

The first link mentions a C++ implementation of TrueSkill that someone coded up on GitHub:
https://github.com/JesseBuesking/trueskill

although the license isn't clear (and it's not clear if TrueSkill is patented or otherwise protected).

Wikipedia has a page that provides the pairwise ELO formulas:
