pgfplotstable: How to sort at several equal values

I sorted a table by X-values ascending.
There are several equal X-values and I need them to be sorted by there corresponding Z-values descending.
And maybe ascending Y-values, if X-values are equal each other and X-values are equal each other.

That means in detail:

Is there an elementary way, to configure the sort key?
