The trick, it turns out, is figuring out if an image has a horizontal or vertical orientation. For anyone trying to do this, here's what I did.

# Create a temporary image object
tempImage = scribus.createImage(10, 10, 10, 10)

# Populate that object with your image
scribus.loadImage(imageFile, tempImage)

# Scale the image but NOT proportionally
scribus.setScaleImageToFrame(scaletoframe=1, proportional=0, name=tempImage)

# Use getImageScale to get the relative scaling in
# the x and y directions
imgx,imgy = scribus.getImageScale(tempImage)

If imgx < imgy, you have an horizontal image, otherwise, a vertical (or square) image. I came up with one set of coordinates for horizontal images and another for vertical and select the appropriate one based on the scaling information. Then I delete tempImage.

# Can't have these cluttering up the page
scribus.deleteObject(tempImage)

So, possibly not the best way to do it but it works and it's all I could think of. Oh, and I offset the x coordinate values on odd numbered pages since I print this double sided and it's offset for a three-hole punch.
