you don't need to change the order if you use the nomodifier option

but why not try this

Code:
/cast [target=focus, nodead, harm] lightning bolt; [target=focus, help, nodead,nomodifer] lesser healing wave; [target=focus, help, nodead, modifier:ctrl] healing wave; [target=focus,help, nodead, modifier:shift] Cure disease
which is just
Code:
/cast [target=focus, nodead, harm] lightning bolt
/cast [target=focus, help, nodead,nomodifer] lesser healing wave
/cast [target=focus, help, nodead, modifier:ctrl] healing wave
/cast [target=focus,help, nodead, modifier:shift] Cure disease
on one line

Note that noharm is not the same as help.

from WowWiki
help & harm

The [help] condition is true when the unit can receive a beneficial effect, e.g., a healing spell. The [harm] condition is true when the unit would get an adverse effect, e.g., a damaging spell.
