How would I create a set of folders in the /tmp directory using AS?

Question

I have a set of folders that whenever I restart my machine they get removed (they're in the /tmp directory as they are temporary cache files).
Right now I'm manually re-creating those folders whenever I restart.
So how could I automatically create the set of folders on startup?
I need to create:
/tmp/fcgi_ipc/
/tmp/fcgi_ipc/dynamic/
I figure I can create an bit of AppleScript and set it to run on startup...but I'm totally clueless on exactly what that AppleScript needs to be.
I've tried various "make new folder at ____" but nothing is cutting it.

Consider ...
set base_Path to "/private/var/tmp/" -- path to 'tmp' folder.
set base_Folder to "fcgi_ipc" -- Desired base folder.
set sub_Folder to "dynamic" -- Sub-folder of base folder.
try -- Try handles 'folder already exists' error.
do shell script ("mkdir " & base_Path & base_Folder) -- Create base folder.
end try
try -- Try handles 'folder already exists' error.
do shell script ("mkdir " & base_Path & base_Folder & "/" & sub_Folder) -- Create sub-folder.
end try
... Naturally, you can hard code it, as well ...
try -- Try handles 'folder already exists' error.
do shell script ("mkdir /private/var/tmp/fcgi_ipc/") -- Create base folder.
end try
try -- Try handles 'folder already exists' error.
do shell script ("mkdir /private/var/tmp/fcgi_ipc/dynamic/") -- Create sub-folder.
end try
... or ...
do shell script ("mkdir -p /private/var/tmp/fcgi_ipc/dynamic/") -- Create all folders at once.
