How about this?

Begin Routine

words = sentence.split()
numWords = len(words)
i = 0
frameCounter = 0
showISI = False

Each Frame

if i <= numWords-1:
    if not showISI:
        text.setText(words[i])
        frameCount = 29 + (len(words[i].split()) * int(0.03*144)) 
        frameCounter+=1
        if frameCounter == frameCount:
            i+=1
            frameCounter = 0
            showISI = True
    if showISI:
        text.setText(" ")
        frameCounter += 1
        if frameCounter == 72:
            frameCounter = 0
            showISI = False
else:
    continueRoutine = False
