  I'll assume you use XSLT 1.0.  If not, there are other

  You can instead use <xsl:sort data-type="number" .../>.

  I'm not sure to understand.  But assuming you have a good
reason to not using data-type="number" :

  After your example, it seems you'll always have exactly
three digits.  So you can use something like the following:

    <xsl:choose>
      <xsl:when test="starts-with(., '00')">
        <xsl:value-of select="substring(., 2)"/>
      </xsl:when>
      <xsl:when test="starts-with(., '0')">
        <xsl:value-of select="substring(., 1)"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="."/>
      </xsl:otherwise>
    </xsl:choose>

  If not, you can use a recursive template that skip leading
zeros one by one.
