Without collations this is a XSLT 1.0 solution:
(restriction is that each single decimal number is less than 256)
$ cat data.xml
<data>
<elem number="3.9.10">a</elem>
<elem number="3.10.1">b</elem>
<elem number="3.9.11">c</elem>
<elem number="3.9.9">d</elem>>
</data>
$ java org.apache.xalan.xslt.Process -in data.xml -xsl dec-coll.xsl | tidy
-q -xml
<?xml version="1.0" encoding="utf-8"?>
<elem number="3.9.9">d</elem>
<elem number="3.9.10">a</elem>
<elem number="3.9.11">c</elem>
<elem number="3.10.1">b</elem>
$ cat dec-coll.xsl
<xsl:stylesheet version="1.0">
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:func="http://exslt.org/functions";
xmlns:ns="namespace"
<xsl:output method="xml" />
<xsl:template match="/data">
<xsl:for-each select="elem">
<xsl:sort select="ns:dec-coll(@number)"/>
<xsl:copy-of select="."/>
</xsl:for-each>
</xsl:template>
<!-- generates hex sequence from decimal numbering, eg. 03090B from 3.9.11
-->
<func:function name="ns:dec-coll">
<xsl:param name="str" />
<xsl:choose>
<xsl:when test="contains($str,'.')">
<func:result select="concat(ns:hex(substring-before($str, '.')),
ns:dec-coll(substring-after($str, '.')))" />
</xsl:when>
<xsl:otherwise>
<func:result select="ns:hex($str)" />
</xsl:otherwise>
</xsl:choose>
</func:function>
<!-- works fine for $num < 256 -->
<func:function name="ns:hex">

Yes, if you're using Saxon then
<xsl:sort select="@number"
collation="http://saxon.sf.net/collation?alphanumeric=yes"/>
should do the job.

you could use a collation that split up the decimal
ranges
(saxon has an alphanumeric collation that would
probably do the job)
