We can run triggers using position only, this way we don´t have these few cycles to determine ordering.
On creation time we populate position, even if it's not set, so for the first time position will match trigger names. When user changes a trigger position we sum 1 to the followers.

"AAB_oops_really_second" afterwards, and so on.  The integer numbering
system doesn't seem very useful/flexible when seen in this light.

letters are more flexible than numbers but some users are number-oriented.

I'm afraid an extra mechanism to determine the order to fire triggers will
confuse programmers if someone decides to use both. Besides that, we have to
expend a few cycles to determine the exact trigger execution order.
