story.isDirty('SomeTitle') looks at the currently rendered *story*
column to determine if the tiddler is in edit mode, even if no changes
have been made to the content, so it *is* the function you want to
use.
In contrast, store.isDirty() looks at the tiddler internal-data
*store* to indicate if anything in the document has been modified.
Unfortunately, however, there is currently no *built-in* (TW core)
tracking for testing a specific tiddler to see if it has been changed.
Fortunately, I've written a plugin to address this:
http://www.TiddlyTools.com/#UnsavedChangesPlugin
adds tracking for individual tiddler changes and provides several
forms of output to display and manage the current list of tiddlers
with unsaved changes.
In addition, after the plugin is installed, you can use the following
javascript expression to test a tiddler to see if it has been changed,
regardless of whether is is being edited at the moment.
config.macros.unsavedChanges.changed.contains('TiddlerTitle')
