function Player() {
  var score;

  this.getScore = function() { return score; }
  this.setScore = function(sc) { score = sc; }
}

function compare(playerA, playerB) {
  return playerA.getScore() - playerB.getScore();
}

var players = [];

players['player1'] = new Player();
players['player2'] = new Player();

Array(players).sort(compare);

I have code that is similar to the above. When I step through the code with a debugger, the compare function never gets called and the array isn't sorted. I'm not sure what's wrong with my code?
