I don't understand how you expect the values a,b,c and so on to be 
treated as numbers.

However let's assume you have different input data

<parent>
<a>1,2,3,4,5,6,7,8</a>
<b>10,20,30,40,50,60,70,80</b>
</parent>

then you can of course convert the string sequence the tokenize function 
gives you to a number sequence:

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:xs="http://www.w3.org/2001/XMLSchema"
   exclude-result-prefixes="xs"
   version="2.0">

   <xsl:template match="parent">
     <xsl:copy>
       <xsl:variable name="l1" as="xs:double*" select="for $item in 
tokenize(a, ',') return xs:double($item)"/>
       <xsl:variable name="l2" as="xs:double*" select="for $item in 
tokenize(b, ',') return xs:double($item)"/>
       <ab>
         <xsl:value-of select="for $p in 1 to count($l1) return ($l2[$p] 
div 10, $l1[$p] div 10)" separator=" "/>
       </ab>
     </xsl:copy>
   </xsl:template>

</xsl:stylesheet>
