Jean-Claude,

The problem is EPSG:3053 uses method 9826 which is LCC west oriented.  I
would appreciate it if you could file a ticket in the PROJ.4 track on this
coordinate system, and I should be able to add support for it in a future
version of PROJ.4 using the new axis orientation support.

Please include any test points you are confident of in the ticket so I
can confirm whatever comes out is right.

Best regards,
