You should use the ImagePlus setPosition method for Hyperstacks.
Here is what the macro setSlice function does:

void setSlice() {
   int n = (int)getArg();
   ImagePlus imp = getImage();
   int nSlices = imp.getStackSize();
   if (n==1 && nSlices==1)
     return;
   else if (n<1 || n>nSlices)
     interp.error("Argument must be >=1 and <="+nSlices);
   else {
     if (imp.isHyperStack())
       imp.setPosition(n);
     else
       imp.setSlice(n);
     }
   resetImage();
}
