New issue 3314 by [email protected]: sqrtdenest strongly depends on the order of .args.
http://code.google.com/p/sympy/issues/detail?id=3314

In a number of places, the result of sqrtdenest differs depending on the order in which the .args of the supplied expressions are traversed. So far the experience has been that the difference in not apparently essential (I am bad at radicals, see https://github.com/sympy/sympy/pull/1395 for more solid opinions), and thus the strategy has been to explicitly sort the .args before using them. It is necessary however to remove the cause for this dependency, instead of working around it by sorting.
