I think that none of patterns for <xsl:number> will match your needs.
I suggest this code instead :

  <xsl:template match="sect">
    <xsl:variable name="sect_nesting">
      <xsl:value-of select="count(ancestor-or-self::sect)"/>
    </xsl:variable>

    <xsl:element name="h{$sect_nesting}">
      <xsl:apply-templates select="title/text()"/>
    </xsl:element>
    <xsl:apply-templates select="*[position() > 1]"/>
  </xsl:template>

It counts the number of <sect> elements that are ancestors of a given
<sect>.
