Your current test

<xsl:when test="parent::orderedlist/orderedlist">

tests whether the listitem that's the current node has a parent which is an
orderlist and which also has a child that is an orderedlist. This is true of
the listitems in any list that has a sublist, which is the opposite of what
you want. 

I suspect you were thinking of

<xsl:when test="parent::orderedlist/parent::orderedlist">

which would do what you want, I think. Though I would be tempted to replace
the whole xsl:choose with

<xsl:apply-templates select="." mode="number"/>

and then

<xsl:template match="orderedlist/listitem" mode="number" priority="2">
  <xsl:number format="1."/> 
</xsl:template> 

<xsl:template match="orderedlist/orderedlist/listitem" mode="number"
priority="3">
  <xsl:number format="A."/> 
</xsl:template>
