0024421: Sewing changes orientations of some subshapes.
In result of following script executing, shell with "bad orientation" is got.

In source compound all faces are forward. After sewing operation, we have 54 "forward"-faces and 2 reversed. As result, shape is not valid in terms of "checkshape" (BRepCheck_BadOrientationOfSubshape).
