Sequence does't apply to sub-groups in common tests?

Same here.
If anyone wants to try out what we're talking about, try the following:

Code:
-module(test_SUITE).

-export([all/0,
    groups/0,
    init_per_suite/1,
    end_per_suite/1,
    init_per_group/2,
    end_per_group/2,
    init_per_testcase/2,
    end_per_testcase/2]).

-export([failing_tc/1, ok_tc/1]).

all() ->
    [{group, test}].

groups() ->
    [{failing_group, [], [failing_tc]},
     {ok_group, [], [ok_tc]},
     {test, [sequence], [{group, failing_group}, {group, ok_group}]}].

init_per_suite(Config) -> Config.
end_per_suite(_Config) -> ok.

init_per_group(_Group, Config) -> Config.
end_per_group(failing_group, _Config) -> {return_group_result, failed};
end_per_group(_Group, _Config) -> ok.

init_per_testcase(_TestCase, Config) -> Config.
end_per_testcase(_TestCase, _Config) -> ok.

failing_tc(_Config) -> 2=3.
ok_tc(_Config) -> ok.


running using:
>run_test -suite test_SUITE -logdir <logdir>
(run_test as described in
http://www.erlang.org/doc/apps/common_test/run_test_chapter.html#id2267273)

it should give (in short):
Code:
- - - - - - - - - - - - - - - - - - - - - - - - - -
test_SUITE:failing_tc could not be executed
Reason: {badmatch,3}
- - - - - - - - - - - - - - - - - - - - - - - - - -

Testing Erlang.group_test.test_SUITE: *** FAILED *** test case 1 of 2
Testing Erlang.group_test.test_SUITE: TEST COMPLETE, 1 ok, 1 failed of 2
test cases


*Even though the second tc should be skipped.*
