// Inside OnPlayerDeath

switch (KillAmounts[killerid])
{
   case 50:
   {
      // do something to promote player
   }
   case 100:
   {
      // do something to promote to lvl 2
   }
}

That's the principle. You could also use if statements (not that it matters in pawn, it does in other languages) but I personally like switches as they look a bit better and it's easier to read most of the time.
