I've just started my first Dark Souls 2 experience and a friend of mine has offered to help out with some of the bosses. I'm trying to summon him for the Pursuer boss fight, but for some reason we cannot connect. I know SL aren't a problem, he's using a SL 30 character whilst I'm using a SL 26 character. The only other thing I can think of is that I'm playing the original DS2 for Xbox 360 whereas he's playing Scholar of The First Sin, also for the 360. Would that make a difference?

Yes, that's exactly why you can't coop (or invade).
Original DS 2 and Scholar are considered two different games, even with the DLC patch for original DS 2.
I guess the non compatibility issue comes from the fact that enemy placement are different between the two games.
Edit : seems like my answer is right for the PC version but I've stumble on different answer for the consoles version. Will continue to dig.
Are either of you a member of the Company of Champions? Summoning is not allowed in this Covenant, and the game is made much more difficult for next to no reward. It's easy to fall prey to this Covenant, as it is one of the first things you can come across in Majula. There are no messages or hints that tell you the nature of this Covenant either, so if you enter it unwittingly, you won't be able to summon your friends, and the game basically becomes NG+.
Additionally, Soul Level is important in Dark Souls 2. If you're grossly overleveled compared to your friend, you won't be able to see their summon sign. The type of soap stone they use is important too. Review and use this page to help calculate what you're doing, and to see what soul levels you can summon.
