Blender Version
Broken: 2.72 official

Short description of error
https://developer.blender.org/rB127330d6c added multi-drag with proportional scaling of values for e.g. Object.scale. A Python-defined property with options={'PROPORTIONAL'} does not scale proportionally however.

Exact steps for others to reproduce the error
Run the following code and try the vector prop in Object tab:

import bpy


class HelloWorldPanel(bpy.types.Panel):
    """Creates a Panel in the Object properties window"""
    bl_label = "Hello World Panel"
    bl_idname = "OBJECT_PT_hello"
    bl_space_type = 'PROPERTIES'
    bl_region_type = 'WINDOW'
    bl_context = "object"

    def draw(self, context):
        layout = self.layout
        ob = context.object

        col = layout.column(True)
        col.prop(ob, "prop")


def register():
    bpy.utils.register_class(HelloWorldPanel)
    bpy.types.Object.prop = bpy.props.FloatVectorProperty(name="PROPORTIONAL", min=-10, max=10, subtype="XYZ", options={'PROPORTIONAL'})


def unregister():
    bpy.utils.unregister_class(HelloWorldPanel)
    del bpy.types.Object.prop

if __name__ == "__main__":
    register()

1.0
2.0
3.0

should become
2.0
4.0
6.0

but instead it will be
2.0
3.0
4.0

BTW: bla_rna.properties[...] does not seem to expose options
