For me the mod doesn't work at all. I run the command fs_game mods/survival and it doesn't load at all.
Edit:
I dropped the files from the rar directly into %localappdata%/plutonium/storage/iw5/ and when I launch, plutonium simply redownloads plutonium_patch_mp.ff and plutonium_code_post_gfx_mp.ff and replaces the files from the mod.
