Just

<xsl:template match="h1[. = 'foo']">
   <xsl:copy-of select="following::p[3]"/>
</xsl:template>

has the same effect, since the node won't be copied if it doesn't exist. :-)

select="following::p(not(position()=3))"

Dunno. It was meant to be used like this! (although one could quibble about 
an XML design in which the position of nodes among their siblings is this 
important ... first and last are often special, but third? :-)

Cheers,
