JCR code take care about numbering of versions. Then we order versions by version number, but we should order versions by date of creation.
Example: we have versions 1.0, 1.1, 1.2 -> restore version 1.1 -> create new version, this version has version number 1.1.0. Version 1.1.0 was create after version 1.2. But we handled with 1.1.0 like it was created before 1.2.

• in version list 1.1.0 is displayed before 1.2
• when max of versions is reached then we remove version 1.1.0 before version 1.2
