There's no special for XSL FO, the same HTML trick applies: draw a table of two
cells and put the first half of items into the first cell and the rest to the
second. Here's an (untested) sample for the last XSL FO draft (2000-03-27):

<xsl:template match="OL">
   <xsl:variable name="threshold" select="(count(LI) + 1) div 2"/>

   <fo:table>
      <fo:column column-width="..."/> <!-- first column -->
      <fo:column column-width="..."/> <!-- second column -->
      <fo:table-body>
         <fo:table-row>
            <fo:table-cell> <!-- First column -->
               <fo:list-block>
                  <xsl:apply-templates 
                       select="LI[position() &lt;=threshold]"/>
               </fo:list-block>
            </fo:table-cell>
            <fo:table-cell> <!-- Second column -->
               <fo:list-block>
                  <xsl:apply-templates 
                       select="LI[position() &gt; $threshold]"/>
               </fo:list-block>
            </fo:table-cell>
         </fo:table-row>
      <fo:table-body>
   </fo:table>
</xsl:template>

<xsl:template match="OL/LI">
   <fo:list-item>
      <fo:list-item-label end-indent="label-end()">
          <xsl:number format="1."/>
      </fo:list-item-label>
      <fo:list-item-body start-indent="body-start()">
          <xsl:apply-templates/>
      </fo:list-item-body>
   </fo:list-item>
</xsl:template>
