Getting the line number from "on menupick"

Well, rev 3.5 introduced something called menu 'tagging' - here's a copy from the IDE change log included with rev 3.5
The menu item specification has been extended to allow a tag to be specified. It is now of the form:
<label> [ '/' [ <accelerator> ] [ '|' <tag> ] ]
Note that the <tag> is optional as is the <accelerator> however, if you want an item with a tag but without the accelerator you need:
<label> '/' '|' <tag>
The <tag> must only be composed of characters from the ASCII character set.
If a menu item has a <tag> then it is the tag string that is passed to menuPick rather than the <label>. This is useful for localization of menu items as you don't need to change the menuPick handler for each language supported.
The following tags should be used to label the standard edit menu items to enable them to be controlled by the system dialogs on Mac OS X (e.g. answer file, ask file etc.):
undo, redo, cut, copy, paste, clear, select all, preferences
Note: You should not mix the use of tags and no tags in Unicode menus. Doing so will cause empty values for all unicode items without tags.
Even though it sounds like it's only for "menubar" menus, tagging works for any type of menu. So you can use this knowledge to make the text:
My Silly Name That I Reuse For Everything/|1
<tab>My Silly Name That I Reuse For Everything/|3
My Silly Name That I Reuse For Everything/|4
And then your menupick will automagically get the 'tag' value as the line number; of course with sub-menus, you get a pipe-delimited list of tags, with the entire hierarchy.
So assuming that you change the text of your menu to the above style, your script could be something like:
on menuPick pItemTag
set the itemDelimiter to "|"
put the last item of pItemTag into tLineNumber
Menu tags also greatly simplify multilingual apps, as we can now just tag the items in our preferred language (or english, for consistency with the MacOSX presets) and work with the tag in our scripts.
