You can try a different approach:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";>

<xsl:template match="/">
	<xsl:apply-templates select="(Salesman/Orders[not(@Order='')])[1]"/>
</xsl:template>

<xsl:template match="Orders">
  <order-val>
  	<xsl:value-of select="@Order"/>
  </order-val>
</xsl:template>

</xsl:stylesheet>

This yields:
<order-val>zzzzzzzzz</order-val>

The select clause chooses the first Orders element that has a non-null Order
attribute.
