Yes, it will be a bit confusing that there are two ways of doing it. But I
don't think you're right about the limitations of the XPath "for"
expression. You can do sorting using the new sort() function defined in XSLT
2.0, and you can switch back into XSLT (e.g. to do apply-templates) by
calling a stylesheet function.
