That expression has the same value for every node being sorted.

Your expression evaluates to the sort key. It doesn't evaluate to a string
containing an expression that evaluates to the sort key. (If you want that,
you need the xx:evaluate() extension function available in some products,
e.g. Saxon and Xalan).

You can use an attribute value template here, order="{$order}"
