Get TestCase order within a TestSuite

Hey guys, I am dealing with an Insight report issue, against RQM v2.0.0.2 and may be you can help me.

I need to sort the TestCases (TC) loaded in a TestSuite (TS). This is a critical requirement asked by the customer.

As you already know, within a TS the user could move up or down a TC, modifying the order of the TC list. Check screenshot:

I pulled the Insight RQM OOTB package and I am not able to identify this TC 'index' value anywhere.

So my question is: Is there any way to get this value in order to sort by TC index within a TS?

Research:
What I did was to get the complete xml generated when requesting a Test Suite and analyze its content.
I found out that there are 'testsuite elements' containing Test Cases with an index. Check the screenshot:

So I guess that my next steps are to play around with Framework Manager and see if I can create a lookup table or something like that?
Do you have any other ideas?

Thanks in advance.
