Rename files based on simple text file

Hello!

New here although not completely new to Unix.
I wonder how I could rename files based on the data found in a simple textfile.
It goes like this:

I have 4 files
Code:
1 ldfgkkfjslkdfjsldkfjsf.wav
2 nndsdflksdjf.wav
3 sdflksjdf jjsdflsdfl.wav
4 dkadsdddd.wav

Textfile.txt looks like this:
Code:
1 ^t Some ^t Data
2 ^t Other ^t Info & Stuff
3 ^t Yet ^t More Data
4 ^t To the ^t End

^t being tab, or some other apropriate separation character

I want files to look like this:
Code:
01 - Some -Data
02 - Other - Info & Stuff
03 - Yet - More Data
04 - To the - End

I realize there's a problem if the text document does not match the number of files but that does not need to be error handled. It does not need to be fool proof, I will do this one folder at a time, checking for errors manually. Each folder contains some 10-30 files. I want leading zeroes up to 9 if possible but it's not extremely important.

Background: These are mediafiles converted from tape archives. The titles are in a separate textfile for each converted tape. Each tapes goes into a separate folder.

NAME
Locale::Codes::LangExt - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangExt; $lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic' $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langext_codes(); @names = all_langext_names(); DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in the IANA language registry. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language registry codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langext('acm','alpha'); $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic. This is the default code set. ROUTINES
code2langext ( CODE [,CODESET] ) langext2code ( NAME [,CODESET] ) langext_code2code ( CODE ,CODESET ,CODESET2 ) all_langext_codes ( [CODESET] ) all_langext_names ( [CODESET] ) Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] ) Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME ) Locale::Codes::LangExt::delete_langext_alias ( NAME ) Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
