The numbering is fine. The melding priority within a single stat is numerical in descending order:
X > IX > VIII > VII > VI > V
Because if you want to put Xs on something you put Xs on it until you can't; then you put IXs on it. If you can't put Xs on it at all, you also cannot put IXs on it at all, so you put VIIIs on it until you can't put VIIIs on it, then you put VIIs on it.
