ADVISE PLS. FAA, CFI

Hello.
I have a "question, problem", maybe you guys can clear me and help me.
Im taking my commercial rating.I guess all of you are aware of the requirements for that.
My 'question problem' is this one.you know that we must have min. 250 hours and 50 X country and bla bla!The thing is, i have a portugues glider license, and 375 hours.I know that those hours will count towards my US hours (so i have been told) but there is one thing.I have 75 X country glider hours, i have several check point x country, distance flights and proficience flights most of them with a durations over 4 hours, and some of them with 8 hours in Indurance "mode".
Now the thing is the FAA, states that x country on power airplanes have to be 50 NM and at least with one landing.
And FAA says that gliders x country as to be made in check points method and return to origin airport.
Ok gliders X country dont need to land, they just need to do those checks points flights and return to airport. The same method as in Portugal.
My question is how can i log my glider X country in my commercial, can i do it? How? if possible, i really wanted, not to spend money on X country since i have this hours.Another thing that i dont understand is they say that at least 10 h must be in airplanes, what they mean about it.
Sorry if my English and writing is
