Have you checked to see if there's even an editor assigned to the category you're looking to submit to? DMOZ used to be much more valuable as Yahoo used it as the basis of its directory (as well as numerous other sites).
That said, that's become less valuable as Yahoo isn't a human-edited directory anymore and is a regular search engine.
Many of the categories don't even have editors assigned as DMOZ has had difficulties in attracting people to take on that role for the past few years (there were even scandals of payoffs for certain sites to be given priority in years past, but they had cracked down a little), so as long as that's the case it's doubtful there will be any movement.
If there isn't an editor assigned, I suggest you apply to become the editor of said category. It's acceptable for someone who wants their site in that category to be an editor as well, as long as they admit that in the application process.
