Hi,
attribute combo (phrase, no trucation, complete field) used in yaz-client test,
from the 1st mail in koha-devel list back in June 23:

    @attr 1=Match-heading @attr 4=1 @attr 5=100 @attr 6=3 "Bentley, Peter, Ed."

looks fine to me, and in my test setup it returns a proper result (only one,
exact authority record matched). Most likely, problem is not in the Koha
authority matching code, but in Zebra itself (it's config, or maybe the
particular version you are using is buggy). BTW, do you have ICU tokenizer
enabled? If yes, there were some known problems with it (completeness and
position attributes not working at all, or not working properly) especially in
not up-to-date zebra versions (see Bug 13751 and Bug 16581).
