I noticed when I was testing different methods that seeds which appeared to have germinated in H2O2 sometimes took a while for sprouts to appear after planting. I'm not sure why, whether the germination stalls after they're taken out or what. Stratification is more reliable for speeding up germination than soaking in peroxide. Were the others that only took a week those that you stratified? I'm not really visualizing the two parts with a long root, any chance of a photo?
