orderby=author

I need to find a way to get this:

[catlist argument1=value1 argument2=value2]

to work.

I have tried both

[catlist category1= category=”book” tags=E numberposts=5 pagination=yes customfield_orderby=LNe order= asc excerpt=yes excerpt_size=55 excerpt_strip=no thumbnail=no thumbnail_class=cat_list_tn category2= category=”book” tags=E numberposts=5 pagination=yes customfield_orderby=FN order= asc excerpt=yes excerpt_size=55 excerpt_strip=no thumbnail=no thumbnail_class=cat_list_tn]

and

[catlist category1 =”book” tags=E customfield_orderby=LNe order= asc category2 =”book” tags=E customfield_orderby=FN order= asc numberposts=5 pagination=yes excerpt=yes excerpt_size=55 excerpt_strip=no thumbnail=no thumbnail_class=cat_list_tn]

but both just results in listing only the last field listed in sort.
