I'ld like to know how to bulk rename functions in IDA, based on some condition.

Example: Rename all functions to Foo_XYZ where the function accesses a certain static variable, for example : dword_12345.

This would help me a lot, because I know that address would be only accessed from functions that can be associated with some logic/functionality in the application.

The IDAScope plugin has similar functionality to rename functions based on the Windows API functions they are calling. You can find a standalone script here that does that http://hooked-on-mnemonics.blogspot.fr/2012/06/automated-generic-function-naming-in.html it should give you an idea how to implement what you are looking for.
