Not 100% sure but is the first one going to do a string compare rather than
a numeric compare?
Or is there a chance that $identity is going to contain a string rather
than a float?

I could be completely wrong of course  ...

Well, there is one little thing I don't get. Why is

if ( $hsp->percent_identity >= "$identity" )

any better than

if ( $hsp->percent_identity >= $identity)

Ie what do quotes do?
