Conditionals not evaluating as expected

For example, let's say you have a custom item with the id test_value of type select and the possible values are for this custom type are, for example, 0, 1, 2 or 3 of type number .

In versions prior to v4.1, you could evaluate a statement to test the value of 0 (zero) as follows:

%[if !%id=test_value%]% it returns true if test value was 0 and false if anything else.

However in version 4.1 you get the following results:

%[if !%id=test_value%]% should return true, if test value was 0 and false if anything else (1,2 or 3). But it in actuality it returns true if the value is 0 2 or 3.
