I've haven't been able to find any resource that expresses stress in values from 0 to 100.

I also had a look at some NMDS resources, and the first I found were two Kruskal's papers that happened to be on my desk (Psychometrika 29, 1-27 and Psychometrika 29, 115-129, both from 1964). Both of these expressed stress in percents. Certainly this is not a convention introduced by the authors of the package, since they are much too young to have done that prior to 1964.
