In a transition, how can I validate the value of a custom field?

Is there a way to do such a thing? For example, I have a field defined with group picker called "queue".

In a particular transition, I'd like to check if the value specified is either A or B and throw an error if the value is neither.

You add "validators" to the transition (similar to conditions and post-functions). See the manual pages at http://confluence.atlassian.com/display/JIRA/Configuring+Workflow

However, I don't know what validators are installed in OnDemand instances, you may find they are too limited to do what you need here.
