I've always found some default shortcuts strange, like having none for 'upload to the default server' (I'd like to use ctrl-shift + U like some other web IDEs, but using ctrl-shift-alt + U to keep defaults as much as possible).
'Simple Paste' is the most generic and the simple form, it gives me no surprise when I want to get some code from another file. So I'd like it to be in the 1st place (ctrl + V)
'Paste From History' is the most specific one between three, so I think it would be better in the last place (ctrl-shift-alt + V)
'Paste' (+format) may be commonly used, so it could be in the 2nd place (ctrl-shift + V). Adding the SHIFT to the combination nicely gives the sensation that the system will do an additional operation (format).
That's just the way I feel. What do you think about it? Does the idea deserve to go into the feature requests?
