Hi Didac, I use JScript and from my experience using JScript "classes" for complex data types is the way to go.
I have also used VBScript Classes and these should fit your requirements.
However, I would recommend reading the Specifics of Usage article
here for special caveats around there usage, paying a close note to the following section:
"in TestComplete’s VBScript projects, you can create class instances only in the same script unit...
...To solve the problem, you can create a helper routine in the unit, in which the class is defined."
