I think I tried to answer a question similar to this on another thread, but here goes.
http://canlii.ca/en/ca/laws/regu/sor-2002-227/latest/sor-2002-227.html(b) the skilled worker must
(i) have in the form of transferable and available funds, unencumbered by debts or other obligations, an amount equal to half the minimum necessary income applicable in respect of the group of persons consisting of the skilled worker and their family members, or
(ii) be awarded the number of points referred to in subsection 82(2) for arranged employment in Canada within the meaning of subsection 82(1).
I have looked at Schedule 3, Question 10 and it seems clear that they are asking for the amount of savings, the amount of liabilities (debt), the total amount of unencumbered funds, so in answer to this question I would say YES you have to include your credit card debt. You could attach a cover note to explain the terms of your repayment plan, with proof that you have been paying it off regularly. Your comment about "sort of arrangement employment" does not sound like it would mitigate the requirement for the required proof of funds. I hope this helps.
