Yes, both David's solution and mine cause a type error to be raised if
they use version="2.0" and an XSLT 2.0 processor.

This one performs with both versions without any error:

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="text"/>

 <xsl:variable name="vrtfResults">
  <r>1</r>
  <r>1.70</r>
  <r>2.25</r>
  <r>3</r>
 </xsl:variable>

 <xsl:param name="optional.one" select="true()" />
 <xsl:param name="optional.two" select="true()" />
 <xsl:param name="optional.three" select="true()" />


       <xsl:template match="/">
         <xsl:variable name="vOne" select=
         "document('')/*/xsl:variable[@name='vrtfOne']"
         />
         <xsl:variable name="vResults" select=
         "document('')/*/xsl:variable[@name='vrtfResults']/*"
         />

         <xsl:value-of select=
         "$vResults[number($optional.one)
                  + number($optional.two)
                  + number($optional.three)
                  + 1
                   ]"/>
       </xsl:template>
</xsl:stylesheet>
