To visit all the actions in the Inbox, (iterating only through the leaves, and skipping their parent group nodes, if there is any indentation), you could write, for example, something like:
Code:
tell application id "OFOC"
tell default document
set lstInboxLeaves to flattened tasks where in inbox is true and number of tasks = 0
repeat with oTask in lstInboxLeaves
set strName to name of oTask
end repeat
end tell
end tell
