While it is harsh he didn't meet the criteria. I don't see that there is anything you can do except see if he can retest in a year's time and try and get his scores up. There will be a whole bunch of people asking for an exception to be made and they won't be able to risk making an exception for anyone in case they set a precedent.
We don't have gifted schools but I know a number of gifted kids who didn't get into the extension classes in middle school because they are not high achievers in all areas.
eta. You want him to retest in April. Is it usually a one shot at it set up or do people often have more than one attempt? If it is unusual you will have to see what reasons have been granted a reset in the past and whether he meets any of them.
