Maybe change \dorlap to \dotextrlap. Remembering that \dotextrlap is for text mode and \domathrlap is for math mode is easier than remembering the difference between \dorlap and \domathrlap. Does it make sense to make tlap and blap behave in the same way? I do not know of any advantage of them right away, but it may be better to be consistent with all commands of one 'category'.
