CLS code to sort biblio by first author and number of authors

mgpapp

Hello,

I am almost done adapting the APA 6th style for another journal but I got stuck needing to sort the bibliography by:
1) First author
2) Number of authors
3) Year of publication

I cannot find the syntax to sort by first author or by number of authors in the CSL specification. Could someone point me to where it is?

Thank you,

Marcos

<sort>
<key macro="author" names-min="1" names-use-first="1"/>
<key macro="author-count"/>
<key macro="issued-sort" sort="ascending"/>
</sort>

with
<macro name="author-count">
<names variable="author">
<name form="count"/>
<substitute>
<names variable="editor"/>
</substitute>
</names>
</macro>
