An XSLT 1.0 solution:

<xsl:stylesheet version="1.0"
 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="vResults" select=
	  "document('')/*/xsl:variable[@name='vrtfResults']/*"
	  />

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