Try this.
<command type="script">
<in>!tuck %PARAM%</in>
<out type="push" extdata="tuck">%PARAM%</out>
<out>#c8#%NAME% #c15#fluffs #c16#$tuck$'s #c15#pillow,</out>
<out>#c15#and tucks #c16#$tuck$ #c15#in gently.</out>
<out>#c8#%NAME% #c27#reads #c16#$tuck$ #c27#a bedtime story.</out>

<out>#c33#SLEEP WELL #c16#$tuck$ #c33#!</out>
</command>
Don't know if that'll work but may be worth a try.
