Presenting three single IATs in a random order on the web

I am trying to have participants complete three single race IATs (Asian, Black, White) in a random order in a middle of Qualtrics survey. To do so, I create three separate scripts by simply modifying the SingleTargetIATPictures script available in the library (Last Modified:03-18-2015 by K. Borchert).

Now, in order to randomize the presentation order, I've created a new script just for batch commands based on a previous thread that I found on this forum (https://www.millisecond.com/forums/Topic12404-3.aspx). However, this is my first time using Inquisit, and I am not sure if the script that I created is correct (see below). Does this look ok? Or, is there an easier way to randomize the order of three IATs? Thanks!

<batch>
/ subjects = (1, 2 of 12)
/ groupassignment = groupnumber
/ file = "SingleIATAsian.iqx"
/ file = "SingleIATBlack.iqx"
/ file = "SingleIATWhite.iqx"
</batch>

<batch>
/ subjects = (3, 4 of 12)
/ groupassignment = groupnumber
/ file = "SingleIATAsian.iqx"
/ file = "SingleIATWhite.iqx"
/ file = "SingleIATBlack.iqx"
</batch>

<batch>
/ subjects = (5, 6 of 12)
/ groupassignment = groupnumber
/ file = "SingleIATBlack.iqx"
/ file = "SingleIATAsian.iqx"
/ file = "SingleIATWhite.iqx"
</batch>

<batch>
/ subjects = (7, 8 of 12)
/ groupassignment = groupnumber
/ file = "SingleIATBlack.iqx"
/ file = "SingleIATWhite.iqx"
/ file = "SingleIATAsian.iqx"
</batch>

<batch>
/ subjects = (9, 10 of 12)
/ groupassignment = groupnumber
/ file = "SingleIATWhite.iqx"
/ file = "SingleIATAsian.iqx"
/ file = "SingleIATBlack.iqx"
</batch>

<batch>
/ subjects = (11, 12 of 12)
/ groupassignment = groupnumber
/ file = "SingleIATWhite.iqx"
/ file = "SingleIATBlack.iqx"
/ file = "SingleIATAsian.iqx"
</batch>

The <batch> elements look okay to me, however, you should deploy to the web and then complete a couple of test runs in any case (always a good idea).

And no, there is no other way to randomize the order of scripts. <batch> elements are the way to go.

Hope this helps.
