I did not check this assumption before my prior post. It is done. 
Actually, it is right.
* In %h_delete , comment all lines and add disp("Hello from %h_delete")
* Rebuild the library exec("buildmacros.sce")
* Quit and restart scilab
plot2d()
e=gce();
delete(e.children(1))
// Here, the primitive is called, because the handle is scalar
// Then, only 2 curves remain over the 3
clf
plot2d()
e=gce();
delete(e.children([1 3]))
// Here, the overloading is performed "Hello from %h_delete" is 
displayed as expected.

Conclusion : The overload is called not only in case of unsupported default
data types, but also in case of unsupported data size for supported data 
types.
