The "\>" is wrong - you should just use ">" or "<".

I suspect your GenBank release does no have "Homo" explicitly in the taxonomy.
Maybe the human entries are indexed only as "homo sapiens". If so, the
[genbank-org:homo] part of the query will not work.

You can quickly check this with:

(srs5) getz -lv  '[genbank-org:homo*]'
(srs4) getz -rep '[genbank-org:homo*]'

Yikes - just tried that here with EMBL 51, and found a really weird one:

% getz -lv  '[embl-org:homo*]'

report of query "[embl-org:homo*]"

.. and the reason is, two sets of OS and OC lines:
