The other way round works:
   <xsl:variable name="loop_num">
      <xsl:choose>
        <xsl:when test="not(//Display_Count)">3</xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="//Display_Count"/>
        </xsl:otherwise>
      </xsl:choose>
    </xsl:variable>

With XSLT 2.0 you could use the much shorter
   <xsl:variable name="loop_num"
                 select="if (not(//Display_Count)) then 3 else 
//Display_Count"/>
