Intent not returning score?

I'm creating a simple android game but I'm not sure what I'm doing wrong here due to being new to android. The first bit of code I have is in the GameView class and returns an integer for how many times a sprite is pressed:

public int getHitCount() {
    return hitCount;

}

It is then returned to the GameActivity class where an intent receives it and then it is supposed to go to the main menu class, I think I've got it being sent to the GameActivity class correctly but I'm not sure why the score is not returned to the main menu. Here is my GameActivity intent:

public void finish(){
    super.finish();
    Intent returnIntent = new Intent(GameActivity.this,MainMenu.class);
    returnIntent.putExtra("GAME_SCORE",gameView.getHitCount());
    setResult(RESULT_OK, returnIntent);

    }

    }

Here is the code I use to display it on the MainMenu class but it isn't working for some reason:

 if (requestCode == SCORE_REQUEST_CODE) {
        // Make sure the request was successful
        if (resultCode == RESULT_OK) {
            if (retIntent.hasExtra("GAME_SCORE")) {
                int scoreFromGame = retIntent.getExtras().getInt("GAME_SCORE");
                tvScore.setText(""+Integer.toString(scoreFromGame));


            }
        }
