I realize you probably want an XSLT 1.0 solution as you posted an XSLT
1.0 stylesheet but as I am currently not sure there is a straightforward
1.0 solution here is an XSLT 2.0 solution:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="group">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:for-each-group select="*" group-adjacent="exists(@sort-order)">
<xsl:choose>
<xsl:when test="current-grouping-key()">
<xsl:apply-templates select="current-group()">
<xsl:sort select="@sort-order" data-type="number"/>
</xsl:apply-templates>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
For above cited input it produces above cited output.
