Expression

  *[name(.) = $sortfield]

will return a node-set of elements whose name equal the string value of the
variable sortfield. In xsl:sort the result is converted to a string, thus if
the node-set contains more that one node, the string value of the first node
in the set is used as the sort key.

See the spec <http://www.w3.org/TR/xslt#element-sort>:

  "When used in xsl:for-each, xsl:sort elements must occur first."

The way around this is e.g.

  <xsl:variable name="sortkey">
    <xsl:choose>
      <xsl:when test="$sort='design'">name</xsl:when>
      <xsl:when test="$sort='stat'">status</xsl:when>
      <xsl:otherwise>id</xsl:otherwise>
     </xsl:choose>
  </xsl:variable>
  <xsl:for-each select="file">
    <xsl:sort select="*[name() = $sortkey]"/>
    ...
  </xsl:for-each>
