How do I track a variable score to my LMS system.

Hello, 

I have created a game using Storyline and I have got a Variable set up to track users scores. I would like to be able to track everyone's score in LMS, as we are offering a prize to the highest score and would need to be able to verify the result.

Does anyone know how to do this - all other articles I have found here are out of date and don't seem to work. 

TIA
