You could use a static-text-dialog-item with right justification:

(make-instance 'static-text-dialog-item :dialog-item-text "Right"
               :text-justification #$tejustRight
               ...)

Or, you can use #_stringWidth to find the size of the string
you want to right justify and then set the pen position (#_MoveTo ...)
before calling #_DrawText (or princ) to draw the label:

? (with-pstrs ((c "foo")) (#_stringwidth c))
18
? (with-pstrs ((c "food")) (#_stringwidth c))
24
?
