This is what I do in my enterprise (OS X Sys admin). I create scripts that need to be run, and their dependencies and copy them into each client locally in a folder under /Library/Scripts/mycompany. That is where every script I ever need to call lives.
Then if I have multiple scripts, like if I have a comparison bracket with an if/then statement and it needs to call two other scripts I will just hard code the full path to my script, which is always /Library/Scripts/mycompany/name_of_script.sh
That way I can centralize it, put it in a directory owned as root. Then I can use launch agents (like cron, or init.d) run these scripts based on how I tell it to.
If I add a script to trigger a log in hook in each user's .bash_profile or in their home directory launchd looks at (this is particular to Mac OS X) it may call for other scripts in /Library/Scripts/mycompany.
It just depends on what you are trying to accomplish here.

filetest
filetest(3pm) Perl Programmers Reference Guide filetest(3pm)
NAME
filetest - Perl pragma to control the filetest permission operators
SYNOPSIS
$can_perhaps_read = -r "file"; # use the mode bits
{
use filetest 'access'; # intuit harder
$can_really_read = -r "file";
}
$can_perhaps_read = -r "file"; # use the mode bits again
DESCRIPTION
This pragma tells the compiler to change the behaviour of the filetest permissions operators, the "-r" "-w" "-x" "-R" "-W" "-X" (see perl-
func).
The default behaviour to use the mode bits as returned by the stat() family of calls. This, however, may not be the right thing to do if
for example various ACL (access control lists) schemes are in use. For such environments, "use filetest" may help the permission operators
to return results more consistent with other tools.
Each "use filetest" or "no filetest" affects statements to the end of the enclosing block.
There may be a slight performance decrease in the filetests when "use filetest" is in effect, because in some systems the extended func-
tionality needs to be emulated.
NOTE: using the file tests for security purposes is a lost cause from the start: there is a window open for race conditions (who is to say
that the permissions will not change between the test and the real operation?). Therefore if you are serious about security, just try the
real operation and test for its success - think in terms of atomic operations.
subpragma access
Currently only one subpragma, "access" is implemented. It enables (or disables) the use of access() or similar system calls. This
extended filetest functionality is used only when the argument of the operators is a filename, not when it is a filehandle.
