What site did you get the MC number from? Maybe there's clarification there.
I only ever see the MC numbers via the thread on 'Gaf, no idea where they source those from. The tracking period for this weeks figures was the 26th Dec to the 1st Jan. The G4U! bundle charted at 14, and was actually the only new release charting for the period.
There's generally three sources for sales figures for Japanese games - Media Create, Dengeki and Famitsu, all of which track over different periods, release at different times and track the information slightly differently, so they never match up. I've not seen the Famitsu figures iM@S, though (and can't find them anyway with any ease) - I suspect it didn't chart high enough.
I'm under the impression that supplies were constrained for the previous bundle, so it's quite possible that it posted a second week of sales that made up part of that difference but wasn't sufficient to chart.
