"doesnt work" isn't very descriptive but count() counts the preceding 
elements in the source, not taking account of the sorting. You probably 
just want position()


Also do

<xsl:variable name="docKey"select="count(preceding::tei:msDesc)"/>

not

<xsl:variable name="docKey">
    <xsl:value-of select="count(preceding::tei:msDesc)"/>

except that you want


<xsl:variable name="docKey"select="position()-1"/>
