you're comparing the wrong variables to each other, so it seems weird to you
but it's actually working as it should
the variable you're checking against should be defaulted to 0, so you're always comparing 10 to 0s, giving you those results
you thought you were comparing <var:cl:score>, but you were using <var:pl:<var:cl:score>> which I think evaluates to <var:pl:15> or <var:pl:4> in your pictures of test cases
either way, it wasn't your score, it was a variable set to 0
