I believe this was supposed to be Rand trying to bend the Pattern to his will. He threatened to do this twice in the book--once to Cadsuane, and once to Graendal's spy, Kerb. If possible, I guess it might be a form of Compulsion--but the effects of ta'veren have always been different. Chance twists around Rand, and people have much looser tongues--but never because of a feeling of worship or necessity for the person to whom they are speaking. It always just happens. With Tuon, BS clearly put Tuon in a mindset where Rand's will was supreme, which mirrors Compulsion closely. But I can't honestly believe that Rand used Compulsion. For one, Nynaeve and Elayne--both of whom are very strong-willed, were absolutely no match for Lanfear's compulsion in the White Tower. A strong will such as Tuon's cannot resist Compulsion. Secondly, Rand is familiar with Compulsion, but he views it as a thing of evil as well, and I can't seeing him use it to further his gains. He's been in many situations in the past where Compulsion could have served him greatly, but he hasn't.
