Aquadijoib solution should work.
However you are better off getting used to not use every tick for something like this. Even though it in this case shouldn't hurt to much, but as you start adding more and more things to every tick events then you will loose performance in the end.
Since you only need the score to update whenever the score changes making a function that update it for you will be a better solution. And you just call this function whenever it have changed same goes for your Health bar.
If you are unsure how to use functions I would highly recommend you to learn how to before you get to far into your game.
