Creating a Form Point Based Variable

Hi

I have tried to create a variable without success to create a point based scoring system based on a runners form. 3 points for first (1), 2 points for 2nd (2) and 1 point for third (3). Points need to be a total of more than 10 to qualify and the total must be the maximum of all horse points. 
Any ideas how to implement this? 

Thanks

Good morning, 

I notice there has been no response on this. Would you prefer I create a ticket for this request? 

Sorry for delay.
It's not trivial but could be done with several IFs.
Please find attached triggers file as an example.

Hi Tim, 

Thank you for this. I was not far off with my original creation so can see what I was doing wrong now. I appreciate your assistance.
