I've often come across this problem and I was always inclined to believe there was no solution to it. But now I seem to have found a working solution.
However, as I was typing this stylesheet out, I had the faint feeling that I later on would regret having posted it...

here's the xsl:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes"/>

<xsl:key name="xID" match="article" use="generate-id()"/>

<xsl:variable name="groupSize" select="2"/>

<xsl:template match="articles">
<xsl:call-template name="group">
	<xsl:with-param name="idList">
	  <xsl:for-each select="article">
		<xsl:sort select="@priority" data-type="number" order="descending" />
		<xsl:value-of select="generate-id()"/>
		<xsl:text>-</xsl:text>
		<xsl:if test="position() mod $groupSize=0 or position()=last()">
			<xsl:text>|</xsl:text>
		</xsl:if>
	  </xsl:for-each>
	</xsl:with-param>
 </xsl:call-template>
</xsl:template>

<xsl:template name="group">
<xsl:param name="idList"/>
<xsl:variable name="PartIdlist" select="substring-before($idList,'|')"/>
<xsl:if test="$PartIdlist">
	<div>
		<xsl:call-template name="animate">
			<xsl:with-param name="idList" select="$PartIdlist"/>
		</xsl:call-template>
	</div>
	<xsl:call-template name="group">
		<xsl:with-param name="idList" select="substring-after($idList,'|')"/>
	</xsl:call-template>
</xsl:if>
</xsl:template>

<xsl:template name="animate">
<xsl:param name="idList"/>
<xsl:variable name="id" select="substring-before($idList,'-')"/>
<xsl:if test="$id">
	<xsl:apply-templates select="key('xID',$id)"/>
	<xsl:call-template name="animate">
		<xsl:with-param name="idList" select="substring-after($idList,'-')"/>
	</xsl:call-template>
</xsl:if>
</xsl:template>

<xsl:template match="article">
  <p><xsl:value-of select="title" /><xsl:value-of select="@priority" /></p>
</xsl:template>

</xsl:stylesheet>
