Use Sprites as Score

So basscily i want to use my sprites for score and upgrade cost and etc on my 2d game just like in the ui text display i dont know how to write the code tho i have a small idea but i clearly cannot write such code. I dont know why but i cannot find an answer enywhere to i looked up alot !
And dont tell me about bitmap fonts since for some reason my ui doesnt scale properly with my camera i belive its because of this script i put on my cam

public class CameraResolutionFix : MonoBehaviour {
	public float orthographicSize = 5;
	public float aspect = 1.33333f;
	void Start()
	{
		Camera.main.projectionMatrix = Matrix4x4.Ortho(
			-orthographicSize * aspect, orthographicSize * aspect,
			-orthographicSize, orthographicSize,
			GetComponent<Camera>().nearClipPlane, GetComponent<Camera>().farClipPlane);
	}
}

if u find a solution for either the scaling or maybe find a code or tutorial for the sprite to score i will be very thankfull !

still need help please
