php in tab title

I am wondering if it is possible to customise the tab title for a view.

I would like to be able to put a result count in the tab for a task list. eg
tab 1 "All tasks (20)"
tab 2 "Outstanding (5)"
tab 3 "Overdue (2)"
tab 4 "Completed (15)"

I can generate the numbers with php, but is it possible to customise the titles?
