<xsl:number/> with no attributes should do the job.

The "from" attribute with level="single" is very rarely used, and in the
XSLT 1.0 spec it's very unclear what its intended meaning is.

> What I want to do is add a sort-order property to each

> 		<Scope id="3" sort-order="2"/>
> 	</Scope>
> 	<Scope id="4" sort-order="2">
> 		<Scope id="5" sort-order="1">
> 			<Scope id="6" sort-order="1"/>
> 			<Scope id="7" sort-order="2"/>
> 		</Scope>
> 		<Scope id="8" sort-order="2">
> 			<Scope id="9" sort-order="1">
> 				<Scope id="10" sort-order="1"/>
> 				<Scope id="11" sort-order="2"/>
> 			</Scope>
> 			<Scope id="12" sort-order="2"/>
> 		</Scope>
> 	</Scope>
> 	<Scope id="13" sort-order="3"/>
> </Data>

> So that, as you can see, the sort-order is counted at
> one level only of the recursive structure.  If there

> children are numbered starting at 1 at that direct
