Certainly sounds like he has a significantly tight posterior tongue tie. 
The bunching, biting and inefficient feeding is typical.

Will mom fingerfeed? Sometimes fingerfeeding with a small, circular 
massage on the tongue with the finger can help bring these little 
tongues forward a bit more.

As for the ped, can you call him when you are sending a baby, and say "I 
know this is not a typical tongue tie, but..." and explain your findings 
and ask if he could try lifting the tongue to get a good look. You could 
always send the mom to NY if she's desperate, or Dr. Coryllos (our 
pediatric surgeon/IBCLC/wonderwoman) will walk any willing doc through 
it on the telephone. Sometimes sending mom in armed with our AAP BF 
section newsletter article will help her get these very restrictive but 
harder to notice frenula treated.

You could start cultivating the youngest ENTs/oral surgeons/pediatric 
surgeons in town. Sometimes calling around and asking if they treat 
tongue ties is enough to open a dialogue. You can share the latest 
research, there are more studies all the time.

Good luck, it is a frustrating situation when you see something others 
do not.
