[One of my favorite eiditons is the Shai lamora -- a newer improved
Eshkol.]
 
The problem? When did ner shabbos get a brachah? 
 
As per Maggid Mishnah [hilchos shabbos 5:1] it's Seder Rav Amram Gaon. If
so this list is NOT Talmudic. -- but a bit later.

No big deal, but it takes away the opportunity to make extrapolations
from this list as somehow foundational.
