My understanding of the World Bank rating is that it includes a number of different factors. As you noted, the labour dispute was not part of those. As far as I'm aware, unless the methodology includes labour disputes, it would not necessarily have an impact on the ranking, except for the fact that you would see the downstream impacts of the labour dispute on the efficiency of the flow of cargo through the port.
