Really, you should be matching a little bit higher up. If you change your
template to 

<xsl:template match="purchaseOrder">
  <quant>
    <xsl:value-of select="sum(items/quantity)"/>
  </quant>
</xsl:template>

this will do what you want.

You can then, if needs be, do an apply-templates of item inside the template
for purchaseOrder.

Hope this helps,
Dave.
