For each node in the set you are sorting, the value of the sort key is the string "@Name". There's no way the system can know that this string is actually an XPath expression that it's supposed to evaluate. There's no way in standard XSLT of supplying XPath expressions in strings, or reading them from the source document. Several products have an evaluate() extension function to do this. Otherwise, for simple cases, use select="*[name()=$sort-key]" if it's an element, or select="@*[name()=$sort-key]" for an attribute.
