sigh dont you guys ever realise the obvious
in onslaught the MATCH score goes up based on ship/fighter/command ship kills
however the PLAYER score goes up based on participating in these kills
say 2 people both shoot at a command ship > both will likely get full score for this, but the match score only goes up once
same goes for captain kills etc, also you get 500 match score for killing a command ship, you only get arround 320? personal score for doing so.
in 1.9 they 'might' have messed player scoring a bit, but the match scoring is the same. so you're just wrong and there's no problem with the scoreboard
