pardon me for continuing to talk to myself, but I found the core problem 
in /etc/lu/sync.log

ERROR: unable to mount zones. Error message follows.
ERROR: Unable to mount zone <myzone> in </.alt.orig>.
zoneadm: zone 'myzone': "/usr/lib/fs/lofs/mount 
/.alt.orig/zones/myzone/root/nonglobdir/sfw-etc 
/.alt.orig/zones/myzone-orig/lu/a/opt/sfw/etc" failed with exit code 111
zoneadm: zone 'myzone': call to zoneadmd failed


Looking at the old BE filesystem the zone dir is indeed renamed.
# ls -l /.alt.orig/zones
total 3
drwx------   5 root     root           6 Jan 17 08:57 myzone-orig


The above mount would never work, but on second glance the parameters 
are actually backwards.  I think the command should have read:
"/usr/lib/fs/lofs/mount /.alt.orig/zones/myzone-orig/lu/a/opt/sfw/etc 
/.alt.orig/zones/myzone/root/nonglobdir/sfw-etc"
