ActiveRecord's test files need to be sorted.

Even when `ActiveSupport::TestCase.test_order = :sorted` is verified.

73 failures, 52 errors, 2 skips
65 failures, 48 errors, 2 skips
63 failures, 49 errors, 2 skips
66 failures, 48 errors, 2 skips
64 failures, 47 errors, 2 skips

$ bundle exec rake test ACTIVERECORD_ONLY=1 TESTOPTS="--seed=63915"

99 failures, 48 errors, 2 skips  --seed 63915
99 failures, 48 errors, 2 skips  --seed 63915

Using `.sort` on my ActiveRecord Rake test files helper.

65 failures, 48 errors, 2 skips
65 failures, 48 errors, 2 skips
