Close, but no cigar. The best place to ask XSLT related
questions is still the XSL list:

THey have a FAQ and an archive there.

The easiest way is to use
<xsl:template match="Item">
<xsl:for-each select="description">
<xsl:sort select="lang"/>
<xsl:if test="position()=1">
<xsl:copy-of select="."/>
</xsl:if>
</xsl:for-each>
<xsl:template>
This is not very efficient if you have a real lot
of descriptions (run time is O(n*log(n)) instead of
O(n)), but then, I don't think there is an efficient
solution without using an extension function for
lexical string comparisions.
