What do you mean "exactly at the boundary"?
When I try your test script here, I see the corresponding tic placed
exactly at the start (1st pixel) of each color segment.  If that's
not what you get, please tell us the terminal type and gnuplot version.
Perhaps it is an old bug that is now fixed.

If it bothers you that the tic is "in" one color block rather than
straddling two, perhaps you be happier with a tic mark that spans
the entire colorbox.  Try  
    set cbtics scale 10.  (or some other suitably large size)
