In VBScript you are not allowed to cast the variable as a particular type when you declare it. That is why you get an error on the statement:
Dim testList as List
I think the problem is that you instantiated a Test Factory. That manages Tests from the Test Plan. But then you try to create a list of Tests using a filer that includes a field that is not part of a Test. Your filter is trying to use the TC_ASSIGN_RCYC field. That is not a field in the Test entity. That is a field in the Test Instance entity.
Are you trying to get a list of Tests from the Test Plan, or a list of Test Instances as seen in the Execution Grid in the Test Lab?
If you are trying to get a list of Test Instances, then you need to use the TSTestFactory instead of the TestFactory.
