Could be two things here. First - yes - that meta tag could most
likely be breaking stuff. I don't know as I run a non-dev edition
locally.
Secondly - and this is what concerns me the most - do not forget CFCs
return data in XML. Either WDDX form or plain XML.
So even though you returned JSON, it was turned into XML. Not
translated, wrapped I should say. You would need to point Spry to a
CFM page instead.
FYI, CF8 fixes this by letting you specify a return format for CFC methods.
