Passing integer from second activity back to first

I'm trying to pass the users integer score from the second activity back to the first using an intent. When I press the back button in the second activity, the score on the first activity just says "Score". I can't figure out why it's not displaying/updating the integer score. Any help would be much appreciated.

First Activity:

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == 1) {
        if(resultCode == RESULT_OK){
            Integer score = data.getIntExtra(SCORE, 0);
            mScore.setText(score.toString());
        }
        if (resultCode == RESULT_CANCELED) {

        }
    }
}//onActivityResult

Second Activity:

@Override
public void onPause(){
    super.onPause();

    Intent returnIntent = new Intent();
    returnIntent.putExtra(TileActivity.SCORE, mScore);
    if(getParent() == null) {
        setResult(RESULT_OK, returnIntent);
    }else{
        getParent().setResult(RESULT_OK, returnIntent);
    }
    //finish();
}
