Why not?
   Dim XmlDocument, Loaded
   Set XmlDocument = Server.CreateObject("Msxml2.DOMDocument.3.0")
   xmlDocument.async = False
   Loaded = xmlDocument.load Server.MapPath("example.xml")
   If Loaded Then
     ' use XPath here
     xmlDocument.setProperty "SelectionLanguage", "XPath"
     xmlDocument.selectNodes ...

Oh, I see, so your problem is not to use selectNodes or selectSingleNode 
in general with classic ASP but to find a way to return a number value.

One way to solve that is to create an XSLT stylesheet on the fly 
inserting the intended XPath expression and extract the result from 
running the transformation.
