You're right, regex sorting works in this way. The problem here is that `Opera/9.80 (VRE; Opera Mini/4.2/28.2794; U; en) Presto/2.8.119 Version/11.10` corresponds to opera mini, not opera. Before sorting, detection...

yes, it's exactly what sorting means. The second call result is indeed incorrect, since input user agent is opera mini, but it's being detected as opera (opera != opera mini).
