I checked salign too. It considers penalties on primary sequence and

This is not how salign functions in general, but this is basically how 
the iterative_structural_align() method functions. It uses an 
SALIGN-generated sequence alignment as the starting point for a 
structural alignment.

But will you pass me the script lines which aligns
structures at 1,2,3,4Angstroms.

You can generate a quality score at any cutoff you desire. Set 
output='QUALITY' and rms_cutoff to the desired cutoff. For the 
iterative_structural_align() a cutoff of 3.5A is used.
