Back in the 1990s, Toho insisted that licensees use the Heisei Godzilla design because they had given the character a mostly consistent look in the films being made at that time. That's why the Heisei Godzilla is the look most often used for the Dark Horse comics, Trendmasters toys, Random House book covers, etc.
Toho isn't so locked on a particular design these days. Partly because they're not currently making new movies, and partly because there wasn't one main design used in the last series of films. From what Toho told me, the artists for the IDW comics have some leeway to choose what version of Godzilla they want to draw.
Criterion packaging artist Bill Sienkiewicz is a Godzilla fan, but I don't think he's a hardcore Godzilla fan so he most likely went for an images that appealed to him. His cover art looks like an interpretation of the 1954 Godzilla to me and I think it works well. The pop-up is clearly the 2002-03 Godzilla, but that was probably something Bill liked rather than what Toho told him to use. If Toho demanded a certain design I'm sure they would have gone with G'54.
