BTW, I think you are missing a parenthesis here:

((nil . ((indent-tabs-mode . t)))

It doesn't seem to make a difference in this case, though.

The manual (info "(emacs)Directory Variables") indeed says:

   If the ‘.dir-locals.el’ file contains multiple different values for a
variable using different mode names or directories, the values will be
applied in an order such that the values for more specific modes take
priority over more generic modes.

I tried, but I can't reproduce this issue here (using the upcoming
Emacs 27 development branch).  I would try using "emacs -Q" to rule
out that there is something in your local configuration which causes
this.

Best regards,
