Attack order is inconsistent (doubles random battle (dev)).
Turn 2: Mr. Mime was faster (hidden power - priority +0) than Electivire (earthquake - priority +0)
Turn 3: Mr. Mime was slower (thunderbolt - priority +0) than Electivire (earthquake - priority +0)
Something perhaps noteworthy is that my Combusken with speed boost was in battle when Mr. Mime was faster. However none of the sources suggest that changes the attack order in the real game.
