I get the correct behavior (no additional selection is needed).
My vim version is 7.2.385.
I did not use sorted annotation but I doubt it has anything to do with it.

Even if it is not documented it makes sense. When "file:" is present
then it limits the tag to the file which is the argument of "file:". If
"file:" does not have any argument then the argument defaults to the
file in which the tag is defined.
That would mean that exported symbols should be generated without
"file:", non-exported symbols should be generated with "file:" which
does not have argument. In addition to this qualified symbols should be
generated with the qualification and with "file:<fn>" where <fn> is the
file name where the symbol is imported as qualified.
Ghci's :ctags does not support qualified symbols :-/
Just to clarify it for myself.
That would mean that the tags file should look like this:
B.x b.hs /^x = 5 :: Int$/;" v file:a.hs
B.x b.hs /^x = 5 :: Int$/;" v file:c.hs
C.x c.hs /^x = B.x+1$/;" v file:a.hs
localAct a.hs /^localAct = do$/;" v file:
x b.hs /^x = 5 :: Int$/;" v
x c.hs /^x = B.x+1$/;" v
... for these files:
=== file a.hs ===
module A () where
import qualified B as B
import qualified C as C
localAct = do
=== file b.hs ===
module B (x) where
x = 5 :: Int
=== file c.hs ===
module C (x) where
import qualified B as B
x = B.x+1
