Using TCL scripts to create labels on a plot

I am looking for a way to attach labels to my plots but I cannot get the text function to work. I am using TCL as my scripting language.

The command is as follows:

text(x, y, index_Offset, ‘VerticalAlignment’, ‘bottom’, ‘HorizontalAlignement’, ‘right’);

Where index_Offset is ‘1’ ‘2’ ‘3’ etc.

The script just blows past the text command without attaching the result to my plot. However, if I halt the script at the text command and copy the command into matlab window the data is added to the plot.
