I see you're using triggers to call functions on the serverside, from the serverside. You can just call them directly:

onActionSetMatchServer(temp.match, temp.vplayer, temp.splayer);

instead of

triggeraction(this.x + 0.5, this.y + 0.5, "SetMatchServer", temp.match, temp.vplayer,temp.splayer);

Generally triggeraction is used to go from client to server, and vice versa.

Personally I'd have a loop watch the players health.

I.e:

PHP Code:

function onCreated() {
  setTimer(0.5);
}

function onTimeout() {
  // Only watch if there's an actual spar.
  if (this.sparring) {
    onWatchSpar();
    setTimer(0.5);
  }
}

// Variables used for sake of example.
// this.player_a = findplayer("whoever");
// this.player_b = findplayer("someoneelse");

function onWatchSpar() {
  // Both players dead?
  if (this.player_a.hearts <= 0 && this.player_b.hearts <= 0) onTie();
  // Player A Alive, and B dead?
  else if (this.player_a.hearts > 0 && this.player_b.hearts <= 0) onWin(this.player_a);
  // Player B Alive, and A dead?
  else if (this.player_b.hearts > 0 && this.player_a.hearts <= 0) onWin(this.player_b);
} 


Personally I think this may be a bit complicated for one of your first scripts :P
