Layering in tiled

Hello, I am currently working on a Flappy Bird clone. I’ve added a score Label on the top right and I noticed that the score is below the pipe, meaning it would cover the score when the pipe moves across the screen. I want to make it so the score is always on top.

function create() {
  // PIPES //
  this.pipes = this.physics.add.group();

  var spawnPipeTimer = this.time.addEvent({
    delay: 3000,
    callback: this.spawnPipe,
    callbackScope: this,
    loop: true
  });

  this.spawnPipe = function () {
    var top_pipe = this.pipes.create(800, -50 , 'top-pipe');
    var btm_pipe = this.pipes.create(800, 650 , 'btm-pipe');

    this.pipes.add(top_pipe)
    this.pipes.add(btm_pipe)
  }
  // SCORE //
  this.score = this.add.text(0,0, "Score")

}

function update(t, dt) {
  // Pipes //

  this.pipes.children.iterate(function(pipe) {
    pipe.setVelocityX(-120);
  });
this.score.setDepth(1);

thxsm
