I've been working with the original poster trying to get things to
work. Here's the error generated when one of my programs, (or any
for that matter) try to read the tiff files in question:

TIFF Error: Wrong data type 3 for field "SubfileType".
Error #1: Bad Image Format

The output from tiffutil is the same. Basically, the internal NeXT
routines cannot be used to read the tiff image. I doubt it's a trans-
fer problem, however, because about 8 of the TIFF's I scanned a few
months ago display correctly under 1.0 without a catch. The problem
only began with 2.0. Also, one of the utility we have on our NeXT's 
is tifftoeps, which also works, as it apparantly doesn't use the
built in NeXT calls to read the image. We can do this transfew, and
then use scene to convert back to TIFF, but we loose all but 2 bits
of the color data. I've yet to try tiffs from other programs on our
macs, however.
