Run multiple scripts in random order

Hi Everyone,
I have three scripts for a psychophysics experiment I am running. Lets call them "arrangement1.m", "arragement2.m" and "arrangement3.m". Each script executes a task and collects participant data.
I need to counterbalance/randomise the sequence of the scripts.
I can call the scripts to run sequentially in the command window, but having them run randomly for each participant would be ideal.
Would really appreciate any suggestions!! Many thanks.

C = {'arrangement1.m', 'arragement2.m', 'arrangement3.m'};
for k = randperm(numel(C))
run(C{k})
end
Also note that the filename can include an absolute/relative path, for which FULLFILE is very useful.

It is not possible to use run, but using feval is. It is also not as easy to specify a full path (best I can tell you need to cd there and back again), but I don't see a fundamental problem. Am I missing something?

Using CD has side-effects: it potentially changes other functions too. The general solution of swapping from RUN to FEVAL (or STR2FUNC etc) plus also changing the search path is not trivial... precisely because it changes the search path, which RUN does not. In some limited circumstances it could be done easily.
