Well if the @linkend is correct, the next things to check are the key 
declaration and the document context. Since I gather your call to key() is 
happening in a document context that doesn't contain your $cite-ref (the 
mods:mods current node is in a separate tree), you'll need to establish the 
correct context for your call to key().

In the old days this would have been

<xsl:for-each select="$cite-ref">
  <xsl:if test="count(.|key('refs',@linkend)[1])=1">FIRST</xsl:if>
</xsl:for-each>

But since you're using that newfangled 2.0-thang, you could do

<xsl:if
  test="$cite-ref is 
key('refs',$cite-ref/@linkend,$cite-ref)[1]">FIRST</xsl:if>

Note the third argument to establish the document context for key().

I hope that helps,
Wendell
