It seems that the management of horizontal dividers is a little bit
buggy. Anyway, replacing the rules for horizontal position management by
a list of graphic directives at "hard-coded" positions works fine.
(Note, as illustrated by the following example, that vertical dividers
do not seem to suffer this bug.)
Grid[Join[{{"First", "Second", "Third"}}, Partition[Range[12], 6]],
Dividers -> {{None, Red, Directive[Red, Dashing[2]],
Directive[Thickness[5], Green], None, None, Orange}, {2 -> Blue,
3 -> Directive[Thickness[3], Orange], -1 -> Pink}}]
You can see the result at
