try

The code works, but the shape doesn't change the visual arrangement in the diagram.
Is it working?
shape.Invalidate();
Setting the Z-Order by itself doesn't fix things. You have to re-order the NestedChildShapes of the diagram.
Take a look at Example.Components that you'll find by opening the VS SDK Samples Browser and look in CustomCode\NestedShapes.cs. Search on FixZOrder.
Note lines like
LinkedElementCollection<ShapeElement> allShapes = movedShape.ParentShape.NestedChildShapes;...allShapes.Move(i, allShapes.Count - 1);
Changing the ZOrder doesn't change the Z-Order! You need to rearrange the content of the diagram's NestedChildShapes, using the Move operation.
See the Example.Components sample that you'll find by opening the VS SDK Samples browser - it will be in somewhere like Program Files\VisualStudio 2005 SDK\2006.09\VisualStudioIntegration\Samples\DSLTools\Example.DesignerCustomizations\Example.Components
Open Dsl\CustomCode\NestedShapes.cs and search in FixZOrder.
Look particularly at lines like
LinkedElementCollection
<ShapeElement> allShapes = movedShape.ParentShape.NestedChildShapes;allShapes.Move(i, allShapes.Count - 1);

It's been a while since the last time I took the examples. They are far better in this version.
