Here is an XSLT 2.0 stylesheet:

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:xs="http://www.w3.org/2001/XMLSchema"
   exclude-result-prefixes="xs"
   version="2.0">

   <xsl:output method="text"/>

   <xsl:template match="/">
     <xsl:for-each-group select="catalog/book" group-by="genre">
       <xsl:sort select="count(current-group())" order="descending"/>
       <xsl:value-of select="concat(genre, ' - ', 
count(current-group()), '&#13;&#10;')"/>
     </xsl:for-each-group>
   </xsl:template>

</xsl:stylesheet>

You can use XSLT 2.0 with Saxon 9 (http://saxon.sourceforge.net/), 
AltovaXML tools (http://www.altova.com/), or Gestalt 
(http://gestalt.sourceforge.net/).
