oops, I kept thinking I'd try and mess with this one, but I forgot until now.
I just checked it out and I guess the big problem is that the context you're using when painting vertex colors can ONLY paint RGB or RGBA.
SO if you want this to work out you probably need to create your own context. The trouble is that all the options in the color painting tool options edit this RGB/RGBA limited context so you'd either have to:
check if 'Alpha' mode is selected first and edit the custom context for each of the settings
or set up a query to see what the settings are on the original context
or you could just make it into a whole different tool altogether
Sorry, man. I don't know very much about these tools so I can't be sure how to work out the details. Hopefully someone else will chime in here who knows more of what they're doing haha

polyColorPerVertex -r 0 -g 1 -b 0.5 -a 0.5 ; which obviously paints both color and alpha
but
polyColorPerVertex -a 0.5 ;
will only change the alpha value
I'm guessing it shouldn't be too hard to fix....
Seems like it was meant to be there, but for some reason it didn't make it in there.

go to 'Color>Create Empty Color Set' (click the little box) then select the 'A' option
now when you use 'Color> Apply Color' it will only paint the alpha
also there was a very nice vertex painting script for maya posted a couple weeks ago.. I'm sure you can dig it up if you go back a couple pages.
