PubMed Central MI has no constant upper-bound though (the upper-bound is related to the entropies of the variables), so you might want to look at one of the normalized versions if that is important to you. Since you want to determine whether strong agreement is associated with a particular nominal outcome class, you could run polytomous logistic regression with nominal class as the dependent variable and 4 binarized (0,1) dummy variables as predictors, representing the 4 ordinal levels (5-1) with level 1 as the corner point.
