Description

sage: A.<x> = AsymptoticRing('x^ZZ * log(x)^ZZ', QQ)
sage: log(x^4).parent()
Asymptotic Ring <x^ZZ * log(x)^ZZ> over Integer Ring

The correct parent should be

Asymptotic Ring <x^ZZ * log(x)^ZZ> over Rational Field

Not tried, but there should be an easy fix in the _create_element_via_parent_ methods.
