The point I'm making is that the spanner was only suppressed in your original example because the value you chose for right.padding was too large -- large enough to put the right text before the left endpoint, which roughly is why the program gave you nothing. If you use \override TextSpanner.bound-details.right.padding = #2 the text is moved out from under the TextScript. You can then override TextScript.staff-padding and TextSpanner.staff-padding to force an alignment. As far as I know, you will have to align them yourself this way because the TextSpanner and TextScript are not grouped. The inner-texts enhancement does offer a grouping of sorts.
