The hub scores are important because if they fall below a certain number (around 72 or 74) the outgoing links become "no follow".
Your profile score is moderated by how many visitors you get per a determinate time period. Hop hopping, forum participation, questions & answers, number of published hubs and number of followers do help but it seems not as much.
The higher the score the more "credibility" you supposedly have. A score in the nineties such as yours is very respectable, especially taking into account the time on this site, number of followers and number of hubs.
