[OS X TeX] Problem with Bibliography sorting

[Sr Sur]

Hy everybody

I have a problem with tho references that have a miss sorting. I am using
the natbib package  (with the author-year sorting) to create the
Bibliography. I assume that when you have two references with the same
authors at same year and same Journal, and the only difference are the pages
of the same  volume (and issue), the citations are sorted by the page...

Any idea that how can I fix the problem??
the .bib with the two references is attached.

Thanks!!
