Numeric variables - issues with tied results

I'm creating an eLearning module that starts with a bit of a self-check on your conflict management style, before you can start learning more about conflict management. I've tried it in many different ways, so the current version is very stripped back and basic to help me navigate the issues I've been having with button sets resetting variables, etc.

The current issue I'm having now though, is that it's all good if you have a clear winner of the variables - that shows up well on the results slide. However if it's a tied result, then I cannot work out a trigger that won't pick up any tied result, including at the bottom, not just at the top. So the attachment I've included doesn't have any triggers for showing a tied result - hopefully someone can help?!
