Can I use an alias extension with built-in commands in Git?

Question

I have the following alias in mine .gitconfig:

freq = !history | cut -c 8- | grep ^git | sort | uniq -c | sort -n -r | head -n 5

It should show the 5 git commands that I use the most. Taken from here: http://alblue.bandlem.com/2011/04/git-tip-of-week-aliases.html (I know the article is out of date)

When I run the command, it does not output anything:

$ git freq
$

But if I run history | cut -c 8- | grep ^git | sort | uniq -c | sort -n -r | head -n 5, the output is:

$ history | cut -c 8- | grep ^git | sort | uniq -c | sort -n -r | head -n
   5 git log
   5 git status
   5 git current
   5 git co master
   4 git co other-branch

I assume this is because it historyis a shell built-in command, and if I change the alias freq, for example. in:

freq = !history

I get:

$ git freq
error: cannot run history: No such file or directory
fatal: While expanding alias 'freq': 'history': No such file or directory
$

Is there any way to make it work?
