Regarding tiff2pdf page ordering:

   It's been a while since I looked at the source to tiff2pdf, but I
remember that it scans all the IFDs in the Tiff file and sorts them
according to some criteria rather than just taking them in linear
order.  Also, as the output from tiffinfo indicates, some of the images
in your file have the Subfile Type set to Multipage Document and others
do not. If you run tiffinfo over the file and compare the Subfile type
tag reported for each image, you might be able to figure out what the
sort order is without studying the source code. Then, all you have to do
is figure out why your images have different SubFile types. If this is a
one time project, you could extract the individual images in different
sequences with tiffcrop and then reassemble them with tiffcp but this
probably won't change the subfile type so it may not help.

Page Number tags seem to be less than reliable in my experience.

What application produced your TIFFs?
