i get the following error in one of my trusted page template files:

NameError: global name 'context' is not defined

Just a guess (the python gurus could answer this for sure), but lambda functions have access to variables in the containing scope, which in your case is the date.sort function. Does date.sort provide access to 'context'?

A quick test would be to get rid of the lambda function and create a named function and see if that works.
