BibTeX, biblatex and biber ⇒ Arranging the references

[bdairmb]

Hi all;
I used the \documentclass{book} style. Also I used \bibliographystyle{agsm}. I have a small problem in the following references:

Raqab, M. & Amin, W. (1996), ‘Some ordering results on order statistics and record values’, IAPQR Trans. 21 (1), pp. 1–8.

Raqab, M. Z. (1997), ‘Bounds based on greatest convex minorants for moments of record values’, Statistics and Probability Letters 36(1), pp. 35–41.

Raqab, M. Z. (2000), ‘On the moments of record values’, Communication in Statistics- Theory Method 29(7), pp. 1631–1647.

Raqab, M. Z. & Asadi, M. (2008), ‘On the mean residual life of records’, Journal of Statistical Planning and Inference 138, pp. 3660–3666.

The problem is: The first reference in the above list must be before the last one because I want the single author to be before multiple authors for the same person.
please help me in solving this problem

Build a minimal working example (MWE) with an attached *.bib file for the bibliography entries. A careful look into the harvard manual should also help.


Best regards
