ELO scores can only be compared across a single pool of players, and those scores you linked to are from computer v computer tournaments only. The absolute scores aren't comparable because you can effectively adjust the absolute score by adjusting the parameters you start the system off with. As far as Im aware no engines compete against humans regularly enough to get an ELO score (presumably because watching a computer thrash human players for a few hundred games isnt that interesting).
