Ghislaine de Felegonde is a Musk Rambler but not a massive one - it's more peach than a vivid orange, though; Gloire de Dijon is a big old climber, buff to peach and has a lovely scent; Schoolgirl is a modern climber but not very good on the scent aspect; Warm Welcome really IS orange, and is a climber, not noted for powerful perfume, alas; Dixieland Linda might do, but is a climber, so better as a pillar rose.
I've not come across any orange ramblers, sorry! Good luck with the search.
