In Nero, a template is a project with preconfigured settings; e.g. CD-ROM (ISO), AudioCD etc.
In the compilation window, try arranging the files by dates by manually dragging them into desired positions. Don't waste a disc yet - burn an image first (.nrg). Open it with ISObuster and sort the files by LBA. If they are in the order you want them to be, you can go ahead and burn your compilation to a disc.
