This seems to be due to an incomplete certificate chain, which is probably also the reason why Comodo's SSL Analyzer says the certificate isn't trusted. Only browsers that have previously cached the intermediate certificate (or those that automatically fetch them) would trust this certificate. Without the chain issue, this would be an A or A+, unless I'm missing something.
