Sadly, no it isn't. In fact, according to the Transformers' Wikia page, the episode was never even dubbed into English.
Darn. It says there are 52 episodes for the set on amazon.com, and it shows theres a total of 52 Energon episodes including that one on tfwiki.net, so I was curious. Maybe amazon meant to put 51.
I just checked the DVDs in the Energon Ultimate Collection, and "Scorponok's Scars" is not listed among the episodes.
A TV Special of Superlink was dubbed into english as the episode 'Distribution' which makes the total number go up to 52. The Japanese version does not count it in the total 52 episodes.
Yeah, it does, actually. The final episode of Superlink is 51, plus the special is 52. The DVD solicit does have a misprint - the set's only got 51 eps on it.
Technically you're both right. It wasn't counted in the total number of episodes, but the total episode count was only 51 episodes for the main series. The dub then went ahead and included it along with the rest of the (now 50) episodes.
The Real question here is..... Why wasn't Scorponok Scars even dubbed at all? The episode was kinda important to Superlink's if you can call it plot.
