Is there a way to select the top two and also anything that ties?

For example if you were looking through stats and you had games that had a scores of 8,6,6,4,3 but i only wanna use the value of the top 2 unless there is a tie so in this case i want to display 8,6,6 but if the scores were 8,6,5,4,3 i would only want to display 8,6.

	<xsl:for-each select="schedule/game">
	<xsl:sort select="pts" data-type="number" order="descending"/>
	<xsl:choose>
	<xsl:when test="position()=1">
		<tr>
			<td>Points</td>
			<td><xsl:value-of select="pts"/></td>
			<td>&#160;&#160;&#160;</td>
			<td><xsl:value-of select="opponent"/></td>
		</tr>
	</xsl:when>
	<xsl:when test="not(position()>2) and pts>0 and position()!=1">
		<tr>
			<td>&#160;&#160;&#160;</td>
			<td><xsl:value-of select="pts"/></td>
			<td>&#160;&#160;&#160;</td>
			<td><xsl:value-of select="opponent"/></td>
		</tr>
	</xsl:when>
	<xsl:otherwise></xsl:otherwise>
	</xsl:choose></xsl:for-each>
