I-TASSER, evaluation of the ranking of model structure outputs and C-score

To whom it may concern,
I have a question regarding the ranking system of the model structures for a given I-TASSER output folder.
Five model structures are obtained per run and both in the result web page and in the downloaded "cscore.txt" file, the model structures are ranked inaccordingly with the C-score. For example, the structure with the highest C-score may rank below a structure with lower C-score.
I would like to know if this ranking has a meanning, or if I should base my further work on the model structure with the highest C-score, regardless of its ranking.
I attached a screenshot of the "cscore.txt" file in which the model structures are ranked, along with their C-scores etc. In the text, I highlighted the sentence that confused me a bit.

Thank you in advance for your help,

Best regards,
Mehmet Erguven.
