Some of us prefer to have our Login Items in a particular order, a preference that was supported by easy drag & drop in early versions of OS X.
Since the dragging & dropping got more cumbersome (in Leopard [?]), it's appeared necessary to drag multiple items all the way down to the bottom of the list to either change their order or insert a new item into the middle of the list.
Good news (in case it hasn't been mentioned before): I just discovered that merely dragging an item below the item beneath it (and un-clicking) automatically moves it to the bottom of the list. (Unfortunately, I've never found a way around the "move multiple items" issue.
)
