*[name()=$filter] returns a set/sequence of element nodes; the contains()
function returns a boolean.

The result of comparing a node-set to a boolean depends on whether you are
running 1.0 (or 2.0 with backwards compatibility enabled) or 2.0.

In either case, I don't think it does what you want. I think you want

test="*[name()=$filter][contains(., $filter_value)]"

But perhaps you don't even want contains(). In your example, you are matching
the whole value, rather than a substring. That suggests that an "=" test is
wanted, not a "contains" test. So:

test="*[name()=$filter][. = $filter_value]"
