Custom Sort via the XSL and custom template?

Question

I am trying to add a sort order to a CQWP. I would like a template style that does the sorting? I have to sort by a field called SortOrder, then I want it to be by file name - here is the code:
I am thinking to do a foreach but not able to get it working? Is there another easier way?
<!--Start Custom Policy Sort-->
    <xsl:template name="PolicySortedBullets" match="Row[@Style='PolicySortedBullets']" mode="itemstyle">

                <xsl:with-param name="UrlColumnName" select="'LinkUrl'"/>

You can use the XSLT <xsl:sort> element to customize your sort order.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:template match="employees">
<xsl:apply-templates>
<xsl:sort select="salary"/>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="employee">
Last: <xsl:apply-templates select="last"/>
First: <xsl:apply-templates select="first"/>
Salary: <xsl:apply-templates select="salary"/>
Hire Date: <xsl:apply-templates select="@hireDate"/>
<xsl:text>
</xsl:text>
</xsl:template>
