in addition to the more generic solutions Michael offered, it's not
clear to me what criterion your sort order is. If it's just a one-off
request and you really just need to process 5 elements in a custom
order there is always the simple but effective

<xsl:apply-templates select="div[2]"/>
<xsl:apply-templates select="div[3]"/>
<xsl:apply-templates select="div[5]"/>
<xsl:apply-templates select="div[1]"/>
<xsl:apply-templates select="div[4]"/>
