I can confirm both the behavior and a usecase for a tagged datetree.  

In org-datetree.el the function org-datetree-find-year-create searches for
the year on a headline and will not match content with anything beyond the
fourth digit.
: (defun org-datetree-find-year-create (year)
:   (let ((re "^\\*+[ \t]+\\([12][0-9][0-9][0-9]\\)$")
: 	match)

In this particular case the tag in question is :noexport: with white space
fore (and maybe aft), and the following change to the regular expression
was tested with success.
: (defun org-datetree-find-year-create (year)
:   (let ((re "^\\*+[ \t]+\\([12][0-9][0-9][0-9]\\)[ \t]+:noexport:[ \t]*$")
: 	match)
Of course this only matches the specific tag in this example *and* only
matches a datetree with this tag. The regular expression needs to be
improved to include a valid tag set as optional.
