ok,my bad. i was transforming list to a set.

a1 = [2, 2, 3]
a2 = [4, 9, 9]
test.assert_equals(comp(a1, a2), False)
a1 = [2, 2, 3]
a2 = [4, 4, 9]
test.assert_equals(comp(a1, a2), True)

Each element counts, repeating or not. If you remove repetitions, then sure - they're "same".. But it doesn't say anywhere in description to do so, so your approach will be incorrect.

10-th and 11-th test in fixed test in Attempt?

They haven't the same input values and both tests expect different output. Nothing wrong with that.

or 10 and 11. [2,3] and [9,4] is repeated 2 times

That's just not true. Look at the inputs again, carefully. There's at least 1 different number.

The test 9 and 10 in the fixed tests have the same input but diffrent output. If you return arrray1 and array2 you can clearly see that.
