Clearly, Avraham had the guests acquire the tongues before slaughtering the animal. As he assumed they were non-Jews, their ownership of the relevant body parts exempts those body parts from the requirement (Shulchan Arukh YD 61:26). Perhaps Avraham gave them water to wash their feet as part of a Kinyan Chalipin (according to Levi (Bava Metzia 47a)).

Alternatively, Avraham may have known that Shem was totoo far away to get the meat before it spoiled and exchanged the meat for money to save the Shem's property value from being lost (Shulchan Arukh YD 61:10).

Finally, perhaps Avraham held like the opinions (Chullin 136a) that giving the tongue doesn't apply in the Diaspora because of a connection in the verse to Terumot and Maaserot. Since Avraham was living before Yerusha and Yeshiva of the land, the Mitzva didn't apply yet to his locale.
