Right. That's how the biologists use the word "taxonomy", and I wish it 
were confined to that use.

This could be expressed by saying that the facet of "disciplines" or 
"fields of knowledge" takes priority over the facet of "entities" in the 
citation order.

I agree, and would call this sort of arrangement "alphabetico-classed". 
As words are used without notation, the arrangement of sibling terms in 
an array has to be alphabetical. When a notation is used it is possible 
to impose an alternative sequence based on some logical principle other 
than alphabetical order.
