Some suggestions:

3. no deliberate obfuscation

s/deliberate//

5. OO always to be used where possible

s/possible/appropriate/

6. Pass by reference

.= ' when appropriate'

9. Do not reinvent wheel always check CPAN

.= ' but do reinvent elliptic wheels'

19. All subroutines to be commented

s/commented/documented/

23. No Global Variables

s/Glo/Needless Glo/

24. use my not local

Repeats 23

28. Do not use $_

WTF? Why not? s/foo/bar/ for @xyzzy;

30. Initialise variables

Repeats 1

32. Where code returns a result it should do so or die with a meaningful error and $!

Always die? Even with errors that aren't fatal?
