This question has been answered already kinda-sorta, but I'd just like to add a tidbit about Tamamo-caster's C-rank Territory Creation as explained in Fate/Extra - hers is that low because "her personality isn't suited for this kinda stuff".

So, yeah. In the end, it's just because Merlin is so flighty that he doesn't mesh well with Territory Creation ('the ability to create a special terrain advantageous to the magus') and Item Construction ('the ability to manufacture magical items').
