The following works similar to a solution recently posted by Jeni:

<xsl:template match="table">
   <xsl:for-each select="row">
      <xsl:sort select="count(col)" 
                data-type="number" order="descending" />
      <xsl:if test="position()=1">
         <xsl:for-each select="col">
            <xsl:value-of select="@align" />
         </xsl:for-each>
      </xsl:if>
   </xsl:for-each>
</xsl:template>

Note: it does not exactly what you describe.
It selects the row with the biggest number of cols and then
concatenates all the values of the align attribute.
Since they are all of length 1, the result will be the expected "rrrr".
