If you only select one node, you have nothing to sort (sorting a list of
length 1 is dull)

XSLt seems more natural if you use the terminoligy that it uses 

the idiom you want is

<xsl:for-each select="/an/x/path"/>
<xsl:sort selct="relative/path/to/sort/key"/>
<xsl:if test="position() &lt; 4">
  do something


selects a set of nodes

For each of these nodes relative/path/to/sort/key is evaluated (relative
to that node) to generate a sort key.

The original node set is then ordered in the ordering specified by thos
sort keys and assigned a position (an integer greater than equal to 1)

For those nodes with a position less than 4, you do something.
