Or you can use the same principle as id() with keys instead because
you only have to define something in your stylesheet to use them. So
define the key:

<xsl:key name="refs" match="ref/*" use="@id" />

and then something like:

<xsl:variable name="x" select="@doc" />
<xsl:for-each select="$sorted-refs">
   <xsl:value-of select="key('refs', $x)/../@number" />
</xsl:for-each>
