Nice find. I did a couple of quick tests and it looks as though file roller is not actually compressing the tar file, and it doesn't matter which compression method is chosen. Not sure why it has this effect on your files as the command works as expected for other files.

Steps to reproduce:
1) In Nautilus, right click on "backlightx" directory, Compress...
2) Select .tar.bz2
3) Resulting file size is 10.2KB

4) Right click on directory, Compress...
5) Select .tar
6) Resulting file size is 10.2KB

7) Right-click on .tar, Compress...
8) Select .bz2
9) Resulting file is 870KB

here file-roller is 'compressing' but will never go below 10.2kB
So - a folder with a number of small files
43.6kB goes to 10.6kB
34kB goes to 10.2kB
15kB goes to 10.2kB
1.5kB goes UP to 10.2kB

The last file-roller in 12.10 to go below 10.2kB was 3.5.3-0ubuntu1 so this changed with the new 3.5.4 release

If this were to be filed upstream it's likely a response one way or the other would gotten quickly
(the file-roller maintainer/dev is usually quite prompt on bug reports
