I don't have any legal background whatsoever, but commonsense says (and that may be an oxymoron, since this is the law & commonsense may not apply), but the limitation is there for a reason, and if she is under that limitation, then she should investigate further. Whether the judge will ding her for being close to the limit is another story. And I think she should ask for the full amount that she can ask for.
It sounds like, though, like she should investigate the costs of filing before she does it--she might be doubly out if she pays for the filing and then the judge docks her for being close to the limit.
Also, she should know that just because she gets a judgment in her favor, that is one thing, and actually collecting the money can be harder than getting the judgment.
