FolderItem.PhysicalFileTotalLengthMBS is the size of resource fork and data
fork.
It does not count extended attributes.

You could ask the Finder for file size with AppleEvents/AppleScripts. Like this:
on getSizeInBytesFromPosixPath(posixPath)
try
set b to (POSIX file posixPath) as string
tell application "Finder" to return size of (b as alias)
on error
return 0
end try
end getSizeInBytesFromPosixPath
