Your call is the wrong way round. You want (e.g.) 
the text "25" at 0.25. Stata's ignoring your label
rules as irrelevant to the data you have. Start with 

mylabels 0(25)100, myscale(@/100) local(label100)

Think "my graph labels that I want are 0(25)100, but 
my data scale is that of the labels divided by 100". 

I invented this beast, but I make the same mistake
too some fraction of the time.
